  Keystone  Tax Free Fund (the  "Fund") is a mutual  fund that seeks the highest
possible  current  income,  exempt from federal income taxes,  while  preserving
capital.  The Fund invests  primarily in municipal  bonds.  The Fund's net asset
value per share will fluctuate in response to changes in the market value of its
portfolio securities.

  The Fund  offers  its shares by direct  investment  only to  shareholders  who
beneficially owned shares of the Fund on December 31, 1990. The Fund also offers
its shares  through  exchanges to  shareholders  of certain other Keystone Group
Funds.

  Your purchase payment is fully invested. There is no sales charge when you buy
the Fund's shares.  The Fund may impose a deferred sales charge,  which declines
from 4% to 1%, if you redeem your shares within four years of purchase.

  The Fund has adopted a Distribution Plan (the "Distribution Plan") pursuant to
Rule 12b-1 under the Investment Company Act of 1940 (the "1940 Act") under which
it bears some of the costs of selling its shares to the public.

  This prospectus  sets forth concisely the information  about the Fund that you
should know before investing. Please read it and retain it for future reference.

  Additional  information  about  the  Fund  is  contained  in  a  statement  of
additional  information and appendix  thereto dated May 1, 1994,  which has been
filed  with the  Securities  and  Exchange  Commission  and is  incorporated  by

<F1>Prior to June 30, 1987,  net  commissions  paid on new sales of shares under the Fund's Rule 12b-1  Distribution  Plan had been
    treated for both  financial  statement  and tax purposes as capital  charges.  On June 11, 1987,  the  Securities  and Exchange
    Commission  adopted a rule which required for financial  statements  for the periods ended on or after June 30, 1987,  that net
    commissions paid under Rule 12b-1 be treated as operating expenses rather than capital charges. Accordingly, beginning with the
    year ended December 31, 1987, the Fund's financial  statements  reflect 12b-1  Distributions  Plan expenses (i.e.,  shareholder
    service fees plus commissions paid net of deferred sales charges received by the Fund) as a component of net investment income.
<F2>Effective  January 1, 1993 the Fund adopted  Statement of Position 93-2:  Determination,  Disclosure,  and Financial  Statement
    Presentation of Income,  Capital Gains and Return of Capital Distributions by Investment Companies.  As a result,  distribution
    amounts  exceeding  book  basis net  investment  income  (or tax basis  net  income on a  temporary  basis)  are  presented  as
    "Distributions in excess of net investment income." Similarly, capital gain distributions in excess of book basis gains (or tax
    basis capital gains on a temporary basis) are presented as  "Distributions in excess of realized capital gains." For the fiscal
    years ended December 31, 1992, 1991 and 1990, distributions in excess of book basis net income were charged to paid-in capital.

FUND DESCRIPTION
- ------------------------------------------------------------------------------
    The  Fund  is  an  open-end,  diversified,  management  investment  company,
commonly known as a mutual fund. The Fund has been operating  continuously since
April 12, 1977 when it was created under  Massachusetts  law as a  Massachusetts
business  trust.  The  Fund  is  one  of  nineteen  funds  managed  by  Keystone
Management, Inc. ("Keystone Management"),  the Fund's investment manager, and is
one of thirty  funds  managed or  advised by  Keystone  Custodian  Funds,  Inc.,
("Keystone") the Fund's investment adviser. Keystone and Keystone Management are
from time to time also collectively referred to as "Keystone."

- ------------------------------------------------------------------------------
FUND OBJECTIVE AND POLICIES
- ------------------------------------------------------------------------------
    The Fund's investment  objective is to provide shareholders with the highest
possible  current  income,  exempt from federal income taxes,  while  preserving
capital. The Fund invests  substantially all and, under ordinary  circumstances,
at least  80% of its  assets  in  federally  tax-exempt  obligations,  including
municipal bonds and notes and tax-exempt  commercial  paper  (municipal  bonds),
which  are  obligations  issued  by or on  behalf  of  states,  territories  and
possessions  of the United  States ("U.S."),  the District of Columbia and their
political subdivisions, agencies and instrumentalities,  the interest from which
is, in the opinion of counsel to the issuers of such bonds,  exempt from federal
income taxes,  including the  alternative  minimum tax.  Municipal bonds include
debt obligations  issued by or on behalf of a political  subdivision of the U.S.
or any agency or  instrumentality  thereof to obtain  funds for  various  public
purposes.  In addition,  municipal  bonds  include  certain  types of industrial
revenue bonds issued by or on behalf of public  authorities to finance privately
operated  facilities.  General  obligation bonds involve the credit of an issuer
possessing  taxing power and are payable from the issuer's general  unrestricted
revenues.  Their payment may be dependent upon an  appropriation by the issuer's
legislative body and may be subject to quantitative  limitations on the issuer's
taxing  power.  Limited  obligation  or revenue  bonds are payable only from the
revenues of a particular facility or class of facilities or, in some cases, from
the proceeds of a special excise or other specific  revenue source,  such as the
user of the facility.  Since the Fund considers  preservation of capital as well
as the level of tax exempt income,  the Fund may realize less income than a fund
willing to expose shareholders" capital to greater risk.

    The Fund invests in municipal bonds only if, at the date of investment, they
are rated  within  the four  highest  grades by  Standard  & Poor's  Corporation
("S&P") (AAA, AA, A and BBB) or by Moody's Investors Service,  Inc.  ("Moody's")
(Aaa, Aa, A and Baa) or, if not rated, are of comparable  quality to obligations
so rated as determined by Keystone. Bonds rated Baa by Moody's are considered to
be medium grade obligations,  i.e., they are neither highly protected nor poorly
secured.  Interest  payments  and  principal  security  appear  adequate for the
present,   but   certain   protective   elements   may  be  lacking  or  may  be
characteristically  unreliable  over any great  length of time.  Such bonds lack
outstanding investment  characteristics and have speculative  characteristics as
well.  Debt rated BBB by S&P is regarded  as having an adequate  capacity to pay
interest and repay principal.  While it normally  exhibits  adequate  protection
parameters,  adverse economic conditions or changing circumstances are generally
more likely to lead to a weakened  capacity to pay interest and repay  principal
for debt in this category than in high rated  categories.  Keystone expects that
under normal  circumstances  at least 65% of the Fund's total assets invested in
municipal  bonds within the three  highest  ratings of such  services or, if not
rated, will be of comparable quality.

    The Tax  Reform Act of 1986 made  significant  changes  in the  federal  tax
status of certain  obligations that previously were fully federally  tax-exempt.
As a result,  three categories of such  obligations  issued after August 7, 1986
now exist:  (1) "public  purpose"  bonds,  the income from which  remains  fully
exempt from federal income taxes; (2) qualified  "private  activity"  industrial
development bonds, the income from which, while exempt from federal income taxes
under Section 103 of the Internal  Revenue Code ("the  Code"),  is includable in
the  calculation  of the  federal  alternative  minimum  tax;  and (3)  "private
activity"  (private  purpose)  bonds,  the income  from which is not exempt from
federal income taxes.  Investments in qualified  "private  activity"  industrial
development bonds will be limited by the Fund's policy of investing no more than
20% of its total assets in securities which pay interest that is not exempt from
federal  taxation.  The Fund  currently  will not invest in  "private  activity"
(private purpose) bonds.

    The Fund also may invest in securities  that pay interest that is not exempt
from federal income taxes, such as corporate and bank  obligations,  obligations
issued  or  guaranteed  by the  U.S.  government  or by any of its  agencies  or
instrumentalities,  commercial paper and repurchase agreements.  Such securities
must be rated at least BBB by S&P or Baa by Moody's  or, if not  rated,  must be
determined  by  Keystone  to be  of  comparable  quality.  However,  except  for
temporary  defensive  purposes,  the Fund will not  invest  more than 20% of its
total assets in such securities.

    The  Fund  also  may  enter  into  reverse  repurchase  agreements  and firm
commitment  agreements for securities  and  currencies.  The Fund may enter into
options  transactions and may write covered call and put options,  purchase call
and put options, including purchasing call and put options to close out existing
positions  and purchase  call options to fix the interest  rates of  obligations
held by it. The Fund may also employ new  investment  techniques  involving such
options.  In  addition,  the Fund may enter into  currency  and other  financial
futures contracts and related options  transactions for hedging purposes and not
for  speculation  and  employ new  investment  techniques  with  respect to such
futures contracts and related options. In addition,  the Fund may also invest in
obligations  denominated  in foreign  currencies  which are exempt from  federal
income tax.

    The ability of the Fund to achieve its  investment  objective  is  dependent
upon the  continuing  ability  of  issuers  of  municipal  bonds  to meet  their
obligations  to pay interest and principal  when due.  Obligations of issuers of
municipal  bonds,  including  municipal bonds issued by them, are subject to the
provisions of  bankruptcy,  insolvency  and other laws  affecting the rights and
remedies of  creditors,  such as the federal  Bankruptcy  Act and laws,  if any,
which may be enacted by congress or state  legislatures  extending  the time for
payment of principal or interest,  or both, or imposing other  constraints  upon
enforcement of such obligations.  There is also the possibility that as a result
of  litigation  or other  conditions,  the power or  ability  of any one or more
issuers to pay, when due, principal and interest on its or their municipal bonds
may be materially affected. In addition, the market for municipal bonds is often
thin and can be  temporarily  affected by large  purchases and sales,  including
those by the Fund.

    From time to time,  proposals have been  introduced  before Congress for the
purpose of  restricting  or  eliminating  the federal  income tax  exemption for
interest on municipal  bonds,  and similar  proposals  may be  introduced in the
future. If such a proposal were enacted, the availability of municipal bonds for
investment by the Fund and the value of the Fund's portfolio could be materially
affected, in which event the Fund would re-evaluate its investment objective and
policies and consider changes in the structure of the Fund or dissolution.

    Investment  in some  securities  may  involve  special  considerations.  For
example,  the Fund may invest in master demand notes, a type of commercial paper
that is  redeemable  on  demand,  but for which  there is no  secondary  market.
Furthermore,  the Fund may enter into repurchase  agreements with domestic banks
and  broker-dealers.  The  payment  of  interest  accrued  by the Fund under its
repurchase  agreements  is dependent on the ability of the seller to perform its
obligations  to the Fund.  If the seller of a  repurchase  agreement  refused to
repurchase the securities underlying the agreement, the Fund would suffer a loss
if the proceeds from the sale of the  underlying  securities  were less than the
agreed upon  repurchase  price,  and the loss would be  increased by any cost of
selling the securities.  If the defaulting seller filed for bankruptcy or became
insolvent,  sale of the securities might be delayed by pending court action.  In
such a case,  it is not clear that the Fund would have the right,  against other
claimants, to keep the securities.

    For  further  information  about the  types of  investments  and  investment
techniques  available  to the Fund,  including  the risks  associated  with such
investments  and  investment  techniques,  see the  section  of this  prospectus
entitled  "Additional  Investment  Information"  and the statement of additional
information.

FUNDAMENTAL NATURE OF INVESTMENT OBJECTIVE
    The investment  objective of the Fund set forth above is fundamental and may
not be changed without the vote of a majority of the Fund's  outstanding  shares
(which  means the  lesser of (1) 67% of the shares  represented  at a meeting at
which more than 50% of the  outstanding  shares are represented or (2) more than
50% of the outstanding  shares).  Of course,  there can be no assurance that the
Fund will achieve its investment  objective  since there is uncertainty in every
investment.

- ------------------------------------------------------------------------------
INVESTMENT RESTRICTIONS
- ------------------------------------------------------------------------------
    The Fund has adopted the fundamental restrictions set forth below, which may
not be changed  without the  approval  of a majority  of the Fund's  outstanding
shares.  These  restrictions and certain other fundamental  restrictions are set
forth in the statement of additional information.

    The Fund may not do the  following:  (1)  invest  more  than 5% of its total
assets in the  securities of any one issuer;  (2) borrow money,  except that the
Fund may borrow  money from banks for  emergency  or  extraordinary  purposes in
aggregate amounts up to one-third  (normally less than 5%) of its net assets and
enter into reverse repurchase agreements;  (3) pledge more than 15% of its total
assets to secure  borrowings;  (4) invest  more than 25% of its total  assets in
securities of issuers in the same industry;  and (5) invest more than 10% of its
total assets in repurchase agreements maturing in more than seven days.

    In addition,  the Fund may,  notwithstanding  any other investment policy or
restriction,  invest all of its assets in the  securities  of a single  open-end
management investment company with substantially the same fundamental investment
objectives,  policies and  restrictions as the Fund. The Fund does not currently
intend to  implement  this policy and would do so only if the  Trustees  were to
determine  such  action  to  be in  the  best  interest  of  the  Fund  and  its
shareholders.  In the event of such  implementation,  the Fund will  comply with
such requirements as to written notice to shareholders as are then in effect.

- ------------------------------------------------------------------------------
RISK FACTORS
- ------------------------------------------------------------------------------
    The risk  inherent  in  investing  in the Fund is that  risk  common  to any
security,  that the net asset  value will  fluctuate  in  response to changes in
economic  conditions,   interest  rates  and  the  market's  perception  of  the
underlying portfolio securities of the Fund.

    The Fund is not intended to constitute a balanced  investment program and is
not designed for investors  seeking capital  appreciation or maximum  tax-exempt
income irrespective of fluctuations in principal or marketability. Shares of the
Fund would not be suitable for tax-exempt  institutions  and may not be suitable
for  certain  retirement  plans  which are  unable to  benefit  from the  Fund's
tax-exempt dividends. In addition, the Fund may not be an appropriate investment
for entities which are "substantial  users" of facilities financed by industrial
development bonds or related persons thereof.

- ------------------------------------------------------------------------------
PRICING SHARES
- ------------------------------------------------------------------------------
    The net asset  value of a Fund share is  computed  each day on which the New
York Stock  Exchange (the  "Exchange") is open as of the close of trading on the
Exchange  (currently  4:00 p.m.  Eastern  time for the  purpose of pricing  Fund
shares) except on days when changes in the value of the Fund's securities do not
affect the  current net asset value of its shares.  The  Exchange  currently  is
closed on weekends, New Year's Day, Presidents' Day, Good Friday,  Memorial Day,
Independence  Day, Labor Day,  Thanksgiving Day and Christmas Day. The net asset
value per share is  arrived  at by  determining  the value of all of the  Fund's
assets,  subtracting  all  liabilities  and dividing the result by the number of
shares outstanding.

    The Fund values  municipal  bonds on the basis of  valuations  provided by a
pricing  service,   approved  by  the  Fund's  Board  of  Trustees,  which  uses
information with respect to transactions in bonds, quotations from bond dealers,
market transactions in comparable  securities and various  relationships between
securities in determining  value.  The Fund values  short-term  instruments with
maturities of sixty days or less at amortized  cost  (original  purchase cost as
adjusted for  amortization  of premium or accretion of  discount),  which,  when
combined with accrued  interest,  approximates  market.  Short-term  instruments
maturing  in more  than  sixty  days for which  market  quotations  are  readily
available are valued at current market value.  Short-term  instruments  maturing
in more than sixty days when purchased  which are held on the sixtieth day prior
to maturity  are valued at  amortized  cost  (market  value on the  sixtieth day
adjusted for  amortization  of premium or accretion of  discount),  which,  when
combined  with  accrued  interest,  approximates  market  and  which in any case
reflects  fair value as  determined  by the Fund's Board of Trustees.  All other
investments  are valued at market  value or,  where  market  quotations  are not
readily  available,  at fair value as  determined  in good faith  using  methods
prescribed by the Fund's Board of Trustees.

- ------------------------------------------------------------------------------
DIVIDENDS AND TAXES
- ------------------------------------------------------------------------------
    The Fund has  qualified  and intends to qualify in the future as a regulated
investment company under the Code. The Fund qualifies if, among other things, it
distributes to its  shareholders  at least 90% of its net investment  income for
its  fiscal  year.  The Fund  also  intends  to make  timely  distributions,  if
necessary, sufficient in amount to avoid the nondeductible 4% excise tax imposed
on a regulated  investment  company to the extent  that it fails to  distribute,
with respect to each calendar year, at least 98% of its ordinary income for such
calendar year and 98% of its net capital gains for the one-year period ending on
October 31 of such calendar year. Any such  distributions  would be (1) declared
on or before December 31 to shareholders of record in December,  (2) paid by the
following  January 31, and (3) includable in the taxable income of  shareholders
for the year in which such  distributions  were declared.  If the Fund qualifies
and if it distributes all of its net investment income and net capital gains, if
any, to shareholders, it will be relieved of any federal income tax liability.

    Commissions  paid by the  Fund on new  sales  of  shares  under  the  Fund's
Distribution Plan (see Distribution Plan) and deferred sales charge receipts are
treated as capital charges and capital credits, respectively, in determining net
investment  income for tax purposes.  For financial  statement  purposes,  these
expenses  and receipts are treated as  operating  expenses  and  revenues.  As a
result,   the  amount  of  dividend   distributions   required  to  satisfy  the
requirements  of the Code might  exceed  net  investment  income  for  financial
statement   purposes,   resulting  in  a  portion  of  such  dividends  being  a
distribution  in  excess  of  net  investment  income  for  financial  statement
purposes, but not for tax purposes.  Total investment return has been unaffected
by both treatments.

    The Fund intends to declare  dividends from net investment  income daily and
distribute  to its  shareholders  such  dividends  monthly  and to  declare  and
distribute all net realized long-term capital gains annually.  All dividends and
distributions will be payable in shares or, at the option of the shareholder, in
cash. All shareholders may receive  dividends in shares without being subject to
a deferred sales charge when such shares are redeemed. Shareholders who have not
opted prior to the record date for any  distribution  to receive  cash will have
the number of such shares  determined on the basis of the Fund's net asset value
per share computed at the end of the day on the record date after adjustment for
the  distribution.  Net asset value is used in computing the number of shares in
both capital gains and income distribution reinvestments. There is a possibility
that  shareholders may lose the tax-exempt status on accrued income on municipal
bonds if shares of the Fund are redeemed  before a dividend  has been  declared.
Account  statements  and/or checks as appropriate will be mailed to shareholders
within seven days after the Fund pays the distribution. Unless the Fund receives
instructions to the contrary from a shareholder  before the record date, it will
assume  that the  shareholder  wishes to receive  that  distribution  and future
capital  gains and income  distributions  in shares.  Instructions  continue  in
effect until changed in writing.

    Under normal  circumstances,  the Fund expects that substantially all of its
dividends  will be  "exempt  interest  dividends,"  which will be treated by its
shareholders  as excludable  from federal  gross income.  In order to pay exempt
interest  dividends,  at the close of each  quarter at least 50% of the value of
the Fund's assets must consist of federally  tax-exempt  obligations.  An exempt
interest  dividend is any  dividend or part  thereof  (other than a capital gain
dividend)  paid  by the  Fund  with  respect  to its  net  federally  excludable
municipal  bond  interest and  designated  as an exempt  interest  dividend in a
written notice mailed to shareholders  not later than sixty days after the close
of its taxable year. The percentage of the total dividends paid by the Fund with
respect to any taxable year which qualifies as exempt interest dividends will be
the same for all shareholders  receiving dividends with respect to such year. If
a shareholder receives an exempt interest dividend with respect to any share and
such share is held for six months or less,  any loss on the sale or  exchange of
such share will be  disallowed  to the  extent of the exempt  interest  dividend
amount.

    Any shareholder who may be a "substantial  user" of a facility financed with
an issue of tax-exempt  obligations or a "related  person" to such a user should
consult his tax adviser  concerning his qualification to receive exempt interest
dividends should the Fund hold obligations financing such facility.

    Under the Tax Reform Act of 1986,  interest  on  certain  "private  activity
bonds" issued after August 7, 1986, although otherwise tax-exempt, is treated as
a tax preference item for alternative minimum tax purposes. Under regulations to
be promulgated,  the Fund's exempt  interest  dividends will be treated the same
way to the extent  attributable to interest paid on such private activity bonds.
Corporate  shareholders should also be aware that the receipt of exempt interest
dividends could subject them to alternative  minimum tax under the provisions of
Section  56(f) of the Code  (relating  generally  to book  income  in  excess of
taxable income).

    Some or all of the Fund's exempt interest  dividends may be subject to state
income taxes. The Fund will report to shareholders on a state by state basis the
sources of its exempt interest dividends.

    Since none of the Fund's  income will  consist of  corporate  dividends,  no
distributions will qualify for the 70% corporate dividends received deduction.

    The Fund  intends  to  distribute  its net  capital  gains as  capital  gain
dividends;  such  dividends  are treated by  shareholders  as long-term  capital
gains.  Such  distributions  will be designated  as capital gain  dividends by a
written  notice  mailed to each  shareholder  no later than sixty days after the
close of the Fund's  taxable  year.  If a  shareholder  receives a capital  gain
dividend and holds his shares for six months or less, then any allowable loss on
disposition  of such shares will be treated as a long-term  capital  loss to the
extent of such capital gain dividend.

    Interest on  indebtedness  incurred or continued by shareholders to purchase
or carry  shares of the Fund  will not be  deductible  for  federal  income  tax
purposes to the extent of the portion of the interest expense relating to exempt
interest  dividends;  that portion is determined by multiplying the total amount
of interest paid or accrued on the indebtedness by a fraction,  the numerator of
which is the exempt interest  dividends received by a shareholder in his taxable
year and the  denominator of which is the sum of the exempt  interest  dividends
and the taxable distributions out of the Fund's investment income and short-term
capital gains received by the shareholder.

    The foregoing is only a summary of some of the important tax  considerations
generally affecting the Fund and its shareholders. No attempt is made to present
a detailed  explanation  of the federal  income tax treatment of the Fund or its
shareholders,  and this  discussion is not intended as a substitute  for careful
tax planning. Accordingly,  potential investors in the Fund are urged to consult
their tax advisers with specific reference to their own tax situation.

    As mentioned  above, at the end of each quarter at least 50% of the value of
the Fund's  assets  must be  invested  in  tax-exempt  obligations  in order for
distributions  to  qualify  as exempt  interest  dividends.  Under  particularly
unusual  circumstances,  such  as when  the  Fund  is in a  prolonged  defensive
investment position,  it is possible that no portion of the Fund's distributions
of income to its  shareholders  for a fiscal year would be exempt  from  federal
income tax;  however,  the Fund does not presently  anticipate that such unusual
circumstances will occur.

    For the fiscal  year ended  December  31,  1993,  approximately  100% of the
Fund's income distributions were designated as exempt from federal income taxes.
The Fund advises its  shareholders  annually as to the federal tax status of all
distributions made during the year.

FUND MANAGEMENT AND EXPENSES
- ------------------------------------------------------------------------------

FUND MANAGEMENT

    Subject to the general supervision of the Fund's Board of Trustees, Keystone
Management,  located at Nevada Financial Center, 3800 Howard Hughes Parkway, Las
Vegas,  Nevada  89109,  serves  as  invest  ment  manager  to  the  Fund  and is
responsible  for the overall  management  of the Fund's  business  and  affairs.
Keystone  Management,  organized  in  1989,  is  a  wholly-owned  subsidiary  of
Keystone,   and  its  directors  and  principal  executive  officers  have  been
affiliated with Keystone,  a seasoned investment adviser, for a number of years.
Keystone  Management  also serves as investment  manager to to each of the other
Keystone  Custodian  Funds and to certain  other funds in the Keystone  Group of
Mutual Funds.

    The Fund pays Keystone  Management  at the end of each calendar  month a fee
for its services consisting of (1) an amount calculated as set forth below:

Annual                                               Aggregate Net Asset Value

and (2) an amount  equal to the  amount of  reimbursable  expenses  of  Keystone
Management accrued during such calendar month.

    Pursuant  to  its  Investment   Management  Agreement  with  the  Fund  (the
"Management  Agreement"),  Keystone  Management  has  delegated  its  investment
management functions,  except for certain administrative and management services
to be  performed  in Nevada,  to  Keystone  and has entered  into an  Investment
Advisory Agreement with Keystone (the "Investment  Advisory  Agreement"),  under
which Keystone provides investment advisory and management services to the Fund.
Services  performed at the office  maintained  in Nevada by Keystone  Management
include (1)  performing  research  and  planning  with respect to (a) the Fund's
qualification as a regulated  investment company under Subchapter M of the Code,
(b) tax  treatment of the Fund's  portfolio  investments,  (c) tax  treatment of
special  corporate  actions  (such as  reorganizations),  (d) state tax  matters
affecting  the Fund,  and (e) the Fund's  distributions  of income  and  capital
gains;  (2)  preparing the Fund's  federal and state tax returns;  (3) providing
services  to the  Fund's  shareholders  in  connection  with  federal  and state
taxation  and  distributions  of  income  and  capital  gains;  and (4)  storing
documents relating to the Fund's activities.

    Keystone, located at 200 Berkeley Street, Boston,  Massachusetts 02116-5034,
has provided investment advisory and management services to investment companies
and private accounts since it was organized in 1932.  Keystone is a wholly-owned
subsidiary of Keystone Group,  Inc.  ("Keystone  Group"),  200 Berkeley  Street,
Boston, Massachusetts 02116-5034.

    Keystone Group is a corporation  privately owned by members of management of
Keystone  and  its  affiliates.  The  shares  of  Keystone  Group  common  stock
beneficially  owned by  management  are held in a number of voting  trusts,  the
trustees  of which  are  George S.  Bissell,  Albert H.  Elfner,  III,  Roger T.
Wickers,  Edward F. Godfrey and Ralph J. Spuehler,  Jr.  Keystone Group provides
accounting,  bookkeeping,  legal,  personnel and general  corporate  services to
Keystone Management, Keystone, their affiliates and the Keystone Group of Mutual
Funds.

    Pursuant to the Investment  Advisory  Agreement,  Keystone  receives for its
services  an annual fee  representing  85% of the  management  fee  received  by
Keystone Management under the Investment Management Agreement.

    For the fiscal year ended  December  31,  1993,  the Fund paid or accrued to
Keystone Management investment management fees of $6,507,055,  which represented
0.43%  of the  Fund's  average  net  assets.  Of such  amount  paid to  Keystone
Management,  $5,530,997  was paid to Keystone for its  services to the Fund.  In
addition, the Fund reimbursed Keystone Management $2,488,890,  which represented
0.16% of the Fund's average net assets, in connection with reimbursable expenses
paid  by  Keystone  Management  on  behalf  of the  Fund  under  the  Investment
Management Agreement. For the fiscal year ended December 31, 1993, the total fee
paid  to  Keystone  Management  by  the  Fund  for  investment   management  and
administrative  services fees was  $8,995,945,  which  represented  0.59% of the
Fund's average net assets.

FUND EXPENSES
    In addition to the investment  advisory and management fees discussed above,
the  principal  expenses  that the Fund is expected to pay include,  but are not
limited to,  expenses of its transfer  agent,  its custodian and its independent
auditors, expenses under its Distribution Plan, fees of its Independent Trustees
("Independent Trustees"), expenses of shareholders' and Trustees' meetings, fees
payable to government agencies, including registration and qualification fees of
the Fund and its shares under  federal and state  securities  laws,  expenses of
preparing,  printing and mailing Fund prospectuses,  notices,  reports and proxy
material and certain extraordinary  expenses. In addition to such expenses,  the
Fund pays its brokerage commissions,  interest charges and taxes. For the fiscal
year ended  December 31, 1993,  the Fund paid 1.66% of its average net assets in
expenses.

    The Fund is subject to certain state annual  expense  limitations,  the most
restrictive of which is as follows:

    2.5% of the first $30 million of Fund average net assets;

    2.0% of the next $70 million of Fund average net assets; and

    1.5% of Fund average net assets over $100 million.

    Capital  charges  and  certain  expenses,  including a portion of the Fund's
Distribution  Plan  expenses,  are not included in the  calculation of the state
expense  limitations.  This  limitation  may be  modified or  eliminated  in the
future.

    During the fiscal year ended  December 31, 1993, the Fund paid or accrued to
Keystone  Investor  Resource  Center,  Inc.  ("KIRC"),  the Fund's  transfer and
dividend disbursing agent,  $29,735 for certain accounting and printing services
and $1,657,577 for shareholder  services.  KIRC is a wholly-owned  subsidiary of
Keystone.  The amount for  shareholder  services  is  included  in the amount of
reimbursable expenses paid on behalf of the Fund by Keystone Management.

PORTFOLIO MANAGER
    Betsy A. Blacher has been the Fund's Portfolio  Manager since 1991. She is a
Keystone Vice President and Senior Portfolio  Manager and has more than 15 years
of investment experience.

SECURITIES TRANSACTIONS
    Keystone  selects  broker-dealers  to  execute  transactions  subject to the
receipt of best execution.  When selecting  broker-dealers  to execute portfolio
transactions  for the Fund,  Keystone  may follow a policy of  considering  as a
factor  the  number  of  shares  of the  Fund  sold by such  broker-dealers.  In
addition,  broker-dealers  may from  time to time be  affiliated  with the Fund,
Keystone  Management,  Keystone,  the  Fund's  principal  underwriter  or  their
affiliates.

PORTFOLIO TURNOVER
    The Fund's portfolio  turnover rates for the fiscal years ended December 31,
1993 and 1992 were 76% and 78%, respectively.

- ------------------------------------------------------------------------------
HOW TO BUY SHARES
- ------------------------------------------------------------------------------
    The Fund offers its shares by direct  investment  only to  shareholders  who
beneficially owned shares of the Fund on December 31, 1990. The Fund also offers
its shares  through  exchanges to  shareholders  of certain other Keystone Group
Funds.

    Shares  of the  Fund may be  purchased  from  any  broker-dealer  that has a
selling agreement with Keystone Distributors, Inc. ("KDI"), the Fund's principal
underwriter  ("Principal  Underwriter").   KDI,  a  wholly-owned  subsidiary  of
Keystone, is located at 200 Berkeley Street, Boston, Massachusetts 02116-5034.

    Shares  become  entitled  to  income  distributions  declared  on the  first
business day following  receipt by the Fund's  transfer agent of payment for the
shares.  It is the  investor's  responsibility  to see that his dealer  promptly
forwards payment to KDI for shares being purchased through the dealer.

    Orders for shares  received by  broker-dealers  prior to that day's close of
trading  on the  Exchange  and  transmitted  to the Fund  prior to its  close of
business  that day will receive the offering  price equal to the net asset value
per share  computed  at the close of  trading on the  Exchange  on the same day.
Orders  received  by  broker-dealers  after that  day's  close of trading on the
Exchange and  transmitted to the Fund prior to the close of business on the next
business day will receive the next business  day's offering  price.  The initial
purchase must be at least $10,000.  Purchase  payments are fully invested at net
asset value.  There are no sales charges on purchases of Fund shares at the time
of purchase.

CONTINGENT DEFERRED SALES CHARGE
    With certain exceptions, when shares are redeemed within four calendar years
after their purchase, a contingent deferred sales charge may be imposed at rates
ranging from a maximum of 4% of amounts  redeemed  during the  calendar  year of
purchase to 1% of amounts redeemed during the third calendar year after the year
of purchase.  No contingent deferred sales charge is imposed on amounts redeemed
thereafter  or  on  shares  purchased  through  reinvestment  of  dividends  and
distributions. If imposed, the contingent deferred sales charge is deducted from
the redemption  proceeds  otherwise  payable to the  shareholder.  Since July 8,
1992, the  contingent  deferred sales charge  attributable  to shares  purchased
prior to  January  1, 1992 has been  retained  by the Fund,  and the  contingent
deferred sales charge attributable to shares purchased after January 1, 1992 is,
to the  extent  permitted  by a new  rule  adopted  by the  NASD,  paid  to KDI.
Accordingly,  for the fiscal year ended  December  31, 1993,  the Fund  retained
$373,564 and KDI received $482,452, respectively, in deferred sales charges.

    The contingent deferred sales charge is a declining percentage of the lesser
of (1) the net asset value of the shares  redeemed or (2) the total cost of such
shares.  No  contingent  deferred  sales  charge is imposed  when a  shareholder
redeems amounts derived from (1) increases in the value of his account above the
total cost of such shares due to  increases  in the net asset value per share of
the  Fund;  (2)  certain  shares  with  respect  to which the Fund did not pay a
commission  on issuance,  including  shares  acquired  through  reinvestment  of
dividend  income and capital gains  distributions;  or (3) shares held in all or
part of more than four consecutive calendar years.

    In determining whether a contingent deferred sales charge is payable and, if
so, the percentage charge applicable, it is assumed that shares held the longest
are the first to be  redeemed.  There is no  deferred  sales  charge  imposed on
exchanges of shares between Keystone funds that have adopted  distribution plans
pursuant  to Rule 12b-1  under the 1940 Act.  Moreover,  when shares of one such
fund have been  exchanged  for shares of another such fund,  for purposes of any
future  contingent  deferred sales charge,  the calendar year of the purchase of
the shares of the Fund exchanged into is assumed to be the year shares  tendered
for exchange were originally purchased.

WAIVER OF DEFERRED SALES CHARGE
    Shares also may be sold, to the extent  permitted by applicable  law, at net
asset value without the payment of  commissions  or the imposition of a deferred
sales charge upon redemption of Fund shares to (1) certain officers,  Directors,
Trustees and employees of the Fund, Keystone Management, Keystone and certain of
their affiliates; (2) registered representatives of firms with dealer agreements
with  KDI;  and (3) a bank or  trust  company  acting  as  trustee  for a single
account.

    In addition,  no contingent deferred sales charge is imposed on a redemption
of  shares  of the  Fund  in  the  event  of  (1)  death  or  disability  of the
shareholder;  (2)  involuntary  redemptions of accounts  having an aggregate net
asset value of less than $1,000; or (3) automatic withdrawals under an automatic
withdrawal plan of up to 1 1/2% per month of the  shareholder's  initial account
balance.

- ------------------------------------------------------------------------------
DISTRIBUTION PLAN
- ------------------------------------------------------------------------------
    The Fund bears some of the costs of selling its shares under a  Distribution
Plan  adopted on June 1, 1983  pursuant  to Rule 12b-1  under the 1940 Act.  The
Fund's  Distribution  Plan  provides  that  the Fund may  expend  up to  0.3125%
quarterly (approximately 1.25% annually) of average daily net asset value of its
shares to pay distribution  costs for sales of its shares and to pay shareholder
service fees. A rule adopted by the NASD,  effective  July 7, 1993,  limits such
annual  expenditures to 1%, of which 0.75% may be used to pay such  distribution
costs and 0.25%  may be used to pay  shareholder  service  fees.  The  aggregate
amount that the Fund may pay for such distribution  costs is limited to 6.25% of
gross share  sales  since the  inception  of the Fund's  Distribution  Plan plus
interest  at the  prime  rate  plus  1% on  unpaid  amounts  thereof  (less  any
contingent deferred sales charges paid by shareholders to KDI).

    Amounts paid under the  Distribution  Plan are paid to the Fund's  Principal
Underwriter,  currently KDI, (1) as  commissions  for Fund shares sold under the
Distribution  Plan, all or any part of which commissions may be reallowed by KDI
to others for selling the Fund shares,  and (2) to enable KDI to pay such others
shareholder  service  fees in respect of shares sold by them after  inception of
the  Distribution  Plan  and  remaining  outstanding  on the  Fund's  books  for
specified  periods.  Amounts  paid or  accrued  to KDI  under (1) and (2) in the
aggregate  may not exceed  the annual  limitation  referred  to above.  From the
amounts received by KDI in connection with the Distribution Plan, and subject to
the  limitations  discussed  above,  KDI  generally  pays  brokers  or  others a
commission  equal to 3% of the  price  paid to the  Fund  for each  sale of Fund
shares as well as a shareholder  service fee at a rate of 0.25% per annum of the
net  asset  value  of  shares  sold by such  brokers  or  others  and  remaining
outstanding on the books of the Fund for specified periods.

    If the Fund is  unable to pay KDI a  commission  on a new sale  because  the
annual  maximum  (0.75% of  average  daily net  assets)  has been  reached,  KDI
intends, but is not obligated, to continue to accept new orders for the purchase
of Fund shares and to pay or accrue  commissions  and service fees to dealers in
excess of the  amount it  currently  receives  from the Fund.  While the Fund is
under  no  contractual  obligation  to pay KDI such  amounts  which  exceed  the
Distribution  Plan limitation,  KDI intends to seek full payment of such charges
from the Fund  (together with interest at the rate of prime plus one percent) at
such time in the future as, and to the extent that,  payment thereof by the Fund
would be within  permitted  limits.  KDI  currently  intends to seek  payment of
interest  only on such charges paid or accrued by KDI  subsequent  to January 1,
1992. If the Fund's  Independent  Trustees  authorize such payments,  the effect
would be to extend the period of time  during  which the Fund incurs the maximum
amount of costs allowed by the Distribution  Plan. If the  Distribution  Plan is
terminated,  KDI will ask the Independent  Trustees to take whatever action they
deem  appropriate  under the  circumstances  with  respect  to  payment  of such
amounts.  If under  changing  conditions KDI were to seek payment of interest on
such amounts,  any such interest  payments also would have to be approved by the
Independent Trustees (and possibly the shareholders).

    During the fiscal year ended December 31, 1993, the Fund recovered  $373,564
in deferred sales charges. During the year, the Fund paid KDI $16,608,165 (1.09%
of the  Fund's  average  daily  net  asset  value  during  the  year)  under the
Distribution Plan, of which $4,272,087 represented repayments of amounts paid by
KDI during the year or in  previous  years in excess of amounts  received by KDI
under the Distribution  Plan. The amount paid by the Fund under its Distribution
Plan,  net of  deferred  sales  charges,  was  $16,234,601  (1.06% of the Fund's
average  daily net asset value during the year).  During the year,  KDI retained
$9,241,496  and paid  commissions  on new sales and service  fees to dealers and
others of  $7,366,669.  In addition,  during the year KDI  received  $482,452 in
deferred sales charges, reducing total advances outstanding to $8,498,955 (0.55%
of the Fund's net asset value as of December 31, 1993).

    The amounts and purposes of expenditures under the Distribution Plan must be
reported to the Independent  Trustees  quarterly.  The Independent  Trustees may
require or approve  changes in the  operation of the  Distribution  Plan and may
require that total  expenditures by the Fund under the Distribution Plan be kept
within limits lower than the maximum amount permitted by the  Distribution  Plan
as stated above. If such costs are not limited by the Independent Trustees, such
costs  could,  for some period of time,  be higher than such costs  permitted by
most other plans presently adopted by other investment companies.

    The  Distribution  Plan may be  terminated at any time by vote of the Fund's
Independent  Trustees or by vote of a majority of the outstanding  voting shares
of the Fund. Any change in the Distribution Plan that would materially  increase
the  distribution  expenses of the Fund  provided for in the  Distribution  Plan
requires shareholder approval.  Otherwise,  the Distribution Plan may be amended
by votes of the majority of both (1) the Fund's Trustees and (2) the Independent
Trustees,  cast in person at a meeting  called for the purpose of voting on such
amendment.

    While the Distribution Plan is in effect, the Fund is required to commit the
selection  and  nomination  of  candidates  for  Independent   Trustees  to  the
discretion of the Independent Trustees.

    Whether any expenditure  under the  Distribution  Plan is subject to a state
expense  limit depends upon the nature of the  expenditure  and the terms of the
state law,  regulation  or order  imposing  the  limit.  A portion of the Fund's
Distribution  Plan  expenses may be  includable  in the Fund's  total  operating
expenses for purposes of determining compliance with state expense limits.

    Upon  written  notice to dealers,  KDI, at its own expense may  periodically
sponsor programs which offer additional compensation in connection with sales of
Fund shares.  Participation  in such programs may be available to all dealers or
to selected dealers who have sold or are expected to sell significant amounts of
shares. Additional compensation may also include financial assistance to dealers
in connection with preapproved  seminars,  conferences and advertising.  No such
programs  or  additional  compensation  will be offered  to the extent  they are
prohibited by the laws of any state or any  self-regulatory  agency, such as the
NASD.

    The  Glass-Steagall  Act  currently  limits  the  ability  of  a  depository
institution  (such as a commercial  bank or a savings and loan  association)  to
become an underwriter  or  distributor  of  securities.  In the event the Glass-
Steagall  Act is deemed  to  prohibit  depository  institutions  from  accepting
payments under the arrangement described above, or should Congress relax current
restrictions  on  depository  institutions,  the Board of Trustees will consider
what action, if any, is appropriate.

    In  addition,  state  securities  laws on this  issue  may  differ  from the
interpretations  of  federal  law  expressed  herein  and  banks  and  financial
institutions may be required to register as dealers pursuant to state law.

- ------------------------------------------------------------------------------
HOW TO REDEEM SHARES
- ------------------------------------------------------------------------------
    Fund shares may be redeemed  for cash at the  redemption  value upon written
order by the  shareholder(s) to the Fund, c/o Keystone Investor Resource Center,
Inc., Box 2121, Boston,  Massachusetts 02106-2121,  and presentation to the Fund
of a properly endorsed share  certificate if certificates have been issued.  The
signature(s) of the shareholder(s) on the written order and certificates must be
guaranteed.  The redemption  value is the net asset value adjusted for fractions
of a cent and may be more or less than the  shareholder's  cost  depending  upon
changes in the value of the Fund's  portfolio  securities  between  purchase and
redemption.  A deferred  sales  charge may be imposed by the Fund at the time of
redemption  of certain  shares as  explained in "How to Buy Shares." If imposed,
the deferred  sales charge is deducted from the  redemption  proceeds  otherwise
payable to the shareholder.

    At various times the Fund may be requested to redeem shares for which it has
not yet received good payment.  In such a case the Fund may delay the mailing of
a redemption  check or the wiring of redemption  proceeds until good payment has
been  collected for the purchase of such shares.  This may take up to 15 days or
more. Any delay may be avoided by purchasing shares with a certified check drawn
on a U.S.  bank or by bank wire of funds.  Although  the mailing of a redemption
check or the wiring of redemption proceeds may be delayed,  the redemption value
will be  determined  and the  redemption  processed  in the  ordinary  course of
business upon receipt of proper documentation.  In such a case, after redemption
and prior to the release of the proceeds,  no appreciation or depreciation  will
occur in the value of the redeemed  shares,  and no interest will be paid on the
redemption proceeds.  If the mailing of a redemption has been delayed, the check
will be mailed or the  proceeds  wired  promptly  after  good  payment  has been
collected.

    The Fund computes the  redemption  value at the close of the Exchange at the
end of the day on  which  it has  received  all  proper  documentation  from the
shareholder.  Payment  of the  amount  due on  redemption,  less any  applicable
deferred sales charge, will be made within seven days thereafter.

    Shareholders also may redeem their shares through their broker-dealers. KDI,
acting as agent for the Fund, stands ready to repurchase Fund shares upon orders
from dealers as follows: redemption requests received by broker-dealers prior to
that day's close of trading on the Exchange and transmitted to the Fund prior to
its  close of  business  that day will  receive  the net  asset  value per share
computed  at the close of trading on the  Exchange  on the same day.  Redemption
requests  received  by  broker-dealers  after that day's close of trading on the
Exchange and  transmitted to the Fund prior to the close of business on the next
business day will  receive the next  business  day's net asset value price.  KDI
will pay the redemption proceeds,  less any applicable deferred sales charge, to
the dealer  placing  the order  within  seven days  thereafter,  assuming it has
received  proper  documentation.  KDI charges no fees for this service,  but the
shareholder's broker-dealer may do so.

    For the protection of shareholders, SIGNATURES ON CERTIFICATES, STOCK POWERS
AND ALL WRITTEN  ORDERS OR  AUTHORIZATIONS  MUST BE GUARANTEED  BY A U.S.  STOCK
EXCHANGE  MEMBER,  A U.S.  COMMERCIAL  BANK OR TRUST  COMPANY  OR OTHER  PERSONS
ELIGIBLE TO GUARANTEE  SIGNATURES UNDER THE SECURITIES  EXCHANGE ACT OF 1934 AND
KIRC'S  POLICIES.  The Fund and KIRC may  waive  this  requirement  but may also
require additional documents in certain cases. Currently,  the requirement for a
signature  guarantee has been waived on redemptions of $50,000 or less where the
account address of record has been the same for a minimum period of 30 days. The
Fund and KIRC reserve the right to withdraw this waiver at any time.

    If the Fund receives a redemption or  repurchase  order but the  shareholder
has not clearly indicated the amount of money or number of shares involved,  the
Fund cannot execute the order. In such cases,  the Fund will request the missing
information  from the shareholder and process the order the day it receives such
information.

TELEPHONE
    Under ordinary circumstances, you may redeem up to $50,000 from your account
by  telephone  by  calling  toll free  1-800-343-2898.  To  engage in  telephone
transactions generally, you must complete the appropriate sections of the Fund's
application.

    In order to insure that  instructions  received by KIRC are genuine when you
initiate a telephone  transaction,  you will be asked to verify certain criteria
specific to your  account.  At the  conclusion of the  transaction,  you will be
given a transaction number confirming your request,  and written confirmation of
your   transaction  will  be  mailed  the  next  business  day.  Your  telephone
instructions will be recorded.  Redemptions by telephone are allowed only if the
address and bank account of record have been the same for a minimum period of 30
days.  If you  cannot  reach  the  Fund by  telephone,  you  should  follow  the
procedures for redeeming by mail or through a broker as set forth above.

GENERAL
    The Fund reserves the right,  at any time,  to terminate,  suspend or change
the  terms  of any  redemption  method  described  in  this  prospectus,  except
redemption by mail, and to impose fees.

    Except  as  otherwise  noted,   neither  the  Fund,  KIRC  nor  KDI  assumes
responsibility for the authenticity of any instructions  received by any of them
from a  shareholder  in  writing,  over the  Keystone  Automated  Response  Line
("KARL") or by telephone. KIRC will employ reasonable procedures to confirm that
instructions  received over KARL or by telephone are genuine.  Neither the Fund,
KIRC nor KDI will be liable when following instructions received over KARL or by
telephone  that KIRC  reasonably  believes  to be  genuine.  If, for any reason,
reasonable procedures are not followed, the Fund, KIRC, or KDI may be liable for
any losses due to unauthorized or fraudulent instructions.

    The Fund may temporarily suspend the right to redeem its shares when (1) the
Exchange is closed,  other than  customary  weekend and  holiday  closings;  (2)
trading on the  Exchange is  restricted;  (3) an  emergency  exists and the Fund
cannot dispose of its  investments or fairly  determine  their value; or (4) the
Securities and Exchange Commission so orders.

SMALL ACCOUNTS
    Because of the high cost of maintaining  small  accounts,  the Fund reserves
the right to redeem  your  account if its value has  fallen  below  $1,000,  the
current minimum  investment level, as a result of your redemptions (but not as a
result of market action). You will be notified in writing and allowed 60 days to
increase the value of your account to the minimum  investment level. No deferred
sales charges are applied to such redemptions.

 REDEMPTIONS IN KIND
    If conditions  arise that would make it undesirable  for the Fund to pay for
all redemptions in cash, the Fund may authorize  payment to be made in portfolio
securities or other property.  However,  the Fund has obligated itself under the
1940 Act to redeem for cash all shares of the Fund  presented for  redemption by
any one  shareholder up to the lesser of $250,000 or 1% of the Fund's net assets
in any 90-day period.  Securities  delivered in payment of redemptions  would be
valued at the same value  assigned to them in computing  the net asset value per
share  and  would,  to the  extent  permitted  by law,  be  readily  marketable.
Shareholders  receiving such  securities  would incur brokerage costs when these
securities are sold.

SHAREHOLDER SERVICES
- ------------------------------------------------------------------------------

    Details on all shareholder services may be obtained from KIRC, by writing or
by calling toll free 1-800-343-2898.

KEYSTONE AUTOMATED RESPONSE LINE
    KARL  offers  you  specific  fund  account  information  and price and yield
quotations  as well as the  ability to effect  account  transactions,  including
investments,  exchanges  and  redemptions.  You may access KARL by dialing toll-
free  1-800-346-3858 on any touch-tone  telephone,  24 hours a day, seven days a
week.

EXCHANGES
    A  shareholder  who has obtained  the  appropriate  prospectus  may exchange
shares  of the Fund for  shares of any of the eight  Keystone  Custodian  Funds,
Keystone Precious Metals Holdings,  Inc., ("KPMH"),  Keystone International Fund
Inc.  ("KIF"),  Keystone  Tax Exempt  Trust  ("KTET") or Keystone  Liquid  Trust
("KLT") on the basis of their  respective  net asset values by calling toll free
1-800-343-2898  or by writing  KIRC at Box 2121,  Boston,  Massachusetts  02106-
2121.  (See "How to Redeem  Shares"  for  additional  information  on  telephone
transactions.)

    Fund  Shares  purchased  by check may be  exchanged  for shares of the named
funds,  other than KPMH or KTET, after 15 days. In order to exchange Fund shares
for  shares of KPMH or KTET,  a  shareholder  must have held Fund  shares  for a
period of at least six months. There is a $10.00 exchange fee for each exchange.
There is no fee for  exchange  orders  received  by the Fund over  KARL.  If the
shares being  tendered for exchange  have been held for less than four years and
are still subject to a deferred sales charge, such charge will carry over to the
shares being acquired in the exchange transaction.  The Fund reserves the right,
after providing the required notice to shareholders,  to terminate this exchange
offer or to change  its  terms,  including  the right to change  the fee for any
exchange.

    Orders to exchange  shares of the Fund for shares of KLT will be executed by
redeeming the shares of the Fund and  purchasing  shares of KLT at the net asset
value of KLT shares  determined  after the proceeds from such redemption  become
available,  which may be up to seven days after  such  redemption.  In all other
cases,  orders for exchanges  received by the Fund prior to 4:00 p.m. on any day
the funds are open for  business  will be executed at the  respective  net asset
values  determined  as of the close of business  that day.  Orders for exchanges
received  after 4:00 p.m. on any business day will be executed at the respective
net asset values determined at the close of the next business day.

    An  excessive  number  of  exchanges  may be  disadvantageous  to the  Fund.
Therefore,  the Fund, in addition to its right to reject any exchange,  reserves
the right to terminate the exchange  privilege of any shareholder who makes more
than five  exchanges  of  shares  of the funds in a year or three in a  calendar
quarter.

    An exchange  order must comply with the  requirements  for a  redemption  or
repurchase  order and must  specify  the dollar  value or number of shares to be
exchanged. Exchanges are subject to the minimum initial purchase requirements of
the fund being acquired.  An exchange  constitutes a sale for federal income tax
purposes.

    The exchange  privilege is available only in states where shares of the fund
being acquired may legally be sold.

AUTOMATIC WITHDRAWAL PLAN
    Under an Automatic  Withdrawal  Plan,  shareholders  may arrange for regular
monthly or quarterly fixed  withdrawal  payments.  Each payment must be at least
$100 and may be as much as 1% per month or 3% per quarter of the total net asset
value  of the Fund  shares  in the  shareholder's  account  when  the  Automatic
Withdrawal  Plan is  opened.  Fixed  withdrawal  payments  are not  subject to a
deferred sales charge.  Excessive  withdrawals may decrease or deplete the value
of a shareholder's account.

OTHER SERVICES
    Under  certain  circumstances  shareholders  may,  within  30  days  after a
redemption, reinstate their accounts at current net asset value.

- ------------------------------------------------------------------------------
PERFORMANCE DATA
- ------------------------------------------------------------------------------
    From time to time, the Fund may advertise  "total  return,"  "current yield"
and "tax equivalent yield." ALL FIGURES ARE BASED ON HISTORICAL EARNINGS AND ARE
NOT INTENDED TO INDICATE FUTURE  PERFORMANCE.  Total return refers to the Fund's
average annual compounded rates of return over specified  periods  determined by
comparing the initial  amount  invested to the ending  redeemable  value of that
amount.  The  resulting  equation  assumes  reinvestment  of all  dividends  and
distributions  and  deduction  of  all  recurring  charges   applicable  to  all
shareholder  accounts.  The deduction of the contingent deferred sales charge is
reflected  in the  applicable  years.  The  exchange  fee is not included in the
calculation.

    Current yield  quotations  represent the yield on an investment for a stated
30-day period computed by dividing net investment income earned per share during
the base period by the maximum  offering  price per share on the last day of the
base period.

    Tax equivalent  yield is, in general,  the current yield divided by a factor
equal to one minus a stated  income  tax rate and  reflects  the yield a taxable
investment  would have to achieve in order to equal on an after-tax  basis a tax
exempt yield.

    The Fund may also include  comparative  performance  and general mutual fund
industry information in advertising or marketing the Fund's shares, such as data
from  Lipper  Analytical   Services,   Inc.  or  other  financial  and  industry
publications.

- ------------------------------------------------------------------------------
FUND SHARES
- ------------------------------------------------------------------------------
    The Fund currently issues one class of shares which  participate  equally in
dividends and distributions and have equal voting, liquidation and other rights.
When issued and paid for, the shares will be fully paid and nonassessable by the
Fund.  Shares may be exchanged as explained  under  "Shareholder  Services," but
will have no other preference, conversion, exchange or preemptive rights. Shares
are redeemable,  transferable and freely assignable as collateral.  There are no
sinking fund provisions.  The Fund may establish additional classes or series of
shares.

    Shareholders  of the Fund are entitled to one vote for each full share owned
and fractional votes for fractional  shares. The Fund will have special meetings
from time to time as required under its  Declaration of Trust and under the 1940
Act. As provided in the Fund's Declaration of Trust, shareholders have the right
to remove  Trustees by an  affirmative  vote of  two-thirds  of the  outstanding
shares.  A  special  meeting  of the  shareholders  will be held when 10% of the
outstanding  shares request a meeting for the purpose of removing a Trustee.  As
prescribed  by Section 16(c) of the 1940 Act,  shareholders  may be eligible for
shareholder communication assistance in connection with the special meeting.

    Under  Massachusetts  law it is possible that a Fund shareholder may be held
personally liable for the Fund's obligations. However, the Fund's Declaration of
Trust provides that shareholders  shall not be subject to any personal liability
for the Fund's obligations and provides indemnification from Fund assets for any
shareholder held personally  liable for the Fund's  obligations.  Disclaimers of
such liability are included in each Fund agreement.

OBLIGATIONS OF FOREIGN BRANCHES OF UNITED STATES BANKS
    The obligations of foreign branches of U.S. banks may be general obligations
of the parent bank in addition to the issuing  branch,  or may be limited by the
terms of a specific obligation and by government regulation. Payment of interest
and principal upon these obligations also may be affected by governmental action
in the  country of domicile of the branch  (generally  referred to as  sovereign
risk).  In  addition,  evidences of  ownership  of such  securities  may be held
outside the U.S.  and the Fund may be subject to the risks  associated  with the
holding of such property overseas. Examples of governmental actions would be the
imposition  of  currency  controls,  interest  limitations,  withholding  taxes,
seizure of assets or the  declaration  of a  moratorium.  Various  provisions of
federal law  governing  domestic  branches  do not apply to foreign  branches of
domestic banks.

OBLIGATIONS OF UNITED STATES BRANCHES OF FOREIGN BANKS
    Obligations of U.S. branches of foreign banks may be general  obligations of
the parent  bank in addition  to the  issuing  branch,  or may be limited by the
terms of a specific obligation and by federal and state regulation as well as by
governmental  action  in the  country  in which  the  foreign  bank has its head
office. In addition,  there may be less publicly  available  information about a
U.S. branch of a foreign bank than about a domestic bank.

MASTER DEMAND NOTES
    Master demand notes are unsecured  obligations that permit the investment of
fluctuating  amounts by the Fund at varying rates of interest pursuant to direct
arrangements  between  the Fund as lender  and the  issuer as  borrower.  Master
demand  notes may  permit  daily  fluctuations  in the  interest  rate and daily
changes on the amounts  borrowed.  The Fund has the right to increase the amount
under the note at any time up to the full amount provided by the note agreement,
or to decrease  the amount,  and the borrower may repay up to the full amount of
the note without  penalty.  Notes  purchased by the Fund must permit the Fund to
demand  payment of principal and accrued  interest at any time (on not more than
seven days notice).  Notes acquired by the Fund may have maturities of more than
one year,  provided  that (1) the Fund is entitled to payment of  principal  and
accrued  interest  upon not more than  seven  days  notice,  and (2) the rate of
interest on such notes is adjusted  automatically  at periodic  intervals  which
normally  will not exceed 31 days but may extend up to one year.  The notes will
be deemed to have a maturity equal to the longer of the period  remaining to the
next interest rate  adjustment or the demand notice period.  Because these types
of notes are direct lending arrangements  between the lender and borrower,  such
instruments are not normally  traded and there is no secondary  market for these
notes,  although they are  redeemable and thus repayable by the borrower at face
value plus accrued interest at any time. Accordingly, the Fund's right to redeem
is  dependent on the ability of the  borrower to pay  principal  and interest on
demand.  In  connection  with master  demand notes,  Keystone  considers,  under
standards  established by the Board of Trustees,  earning  power,  cash flow and
other  liquidity  ratios of the  borrower  and will  monitor  the ability of the
borrower to pay principal and interest on demand.  These notes are not typically
rated by credit rating agencies.  Unless rated, the Fund may invest in them only
if at the time of an investment  the issuer meets the criteria  established  for
commercial  paper  discussed in the Statement of Additional  Information,  which
limit such  investments to commercial paper rated A-1 by S&P, Prime-1 by Moody's
and F-1 by Fitch Investors Service, Inc.

REPURCHASE AGREEMENTS
    The Fund may enter  into  repurchase  agreements  with  member  banks of the
Federal Reserve System which have at least $1 billion in assets, primary dealers
in U.S.  government  securities  or other  financial  institutions  believed  by
Keystone to be creditworthy.  Such persons are required to be registered as U.S.
government securities dealers with an appropriate regulatory organization. Under
such agreements, the bank, primary dealer or other financial institution agrees,
upon entering into the contract, to repurchase the security at a mutually agreed
upon  date and  price,  thereby  determining  the yield  during  the term of the
agreement.  This  results  in a  fixed  rate of  return  insulated  from  market
fluctuations during such period. Under a repurchase  agreement,  the seller must
maintain the value of the  securities  subject to the agreement at not less than
the  repurchase  price,  and such value will be  determined  on a daily basis by
marking the underlying securities to their market value. Although the securities
subject to the repurchase  agreement might bear maturities exceeding a year, the
Fund  only  intends  to enter  into  repurchase  agreements  which  provide  for
settlement  within a year and usually within seven days.  Securities  subject to
repurchase  agreements  will be held by the Fund's  custodian  or in the Federal
Reserve book entry  system.  The Fund does not bear the risk of a decline in the
value of the underlying security unless the seller defaults under its repurchase
obligation.  In the  event of a  bankruptcy  or other  default  of a seller of a
repurchase  agreement,  the Fund could experience both delays in liquidating the
underlying securities and losses including (1) possible declines in the value of
the underlying  securities during the period while the Fund seeks to enforce its
rights thereto;  (2) possible  subnormal  levels of income and lack of access to
income during this period;  and (3) expenses of enforcing its rights.  The Board
of Trustees has established  procedures to evaluate the creditworthiness of each
party with whom the Fund enters into repurchase agreements by setting guidelines
and  standards  of review for Keystone and  monitoring  Keystone's  actions with
regard to repurchase agreements.

REVERSE REPURCHASE AGREEMENTS
    Under a reverse  repurchase  agreement,  the Fund would sell  securities and
agree to  repurchase  them at a mutually  agreed  upon date and price.  The Fund
intends to enter into reverse repurchase agreements to avoid otherwise having to
sell  securities  during   unfavorable   market  conditions  in  order  to  meet
redemptions. At the time the Fund enters into a reverse repurchase agreement, it
will establish a segregated account with the Fund's custodian  containing liquid
assets such as U.S.  government  securities or other high grade debt  securities
having a value not less than the repurchase price (including  accrued  interest)
and  subsequently  will  monitor  the account to  maintain  such value.  Reverse
repurchase  agreements  involve the risk that the market value of the securities
which the Fund is  obligated  to  repurchase  may decline  below the  repurchase
price.  Borrowing and reverse  repurchase  agreements  magnify the potential for
gain or loss on the portfolio  securities of the Fund and,  therefore,  increase
the possibility of fluctuation in the Fund's net asset value. Such practices may
constitute  leveraging.  In the event the  buyer of  securities  under a reverse
repurchase  agreement files for bankruptcy or becomes  insolvent,  such buyer or
its trustee or receiver may receive an extension of time to determine whether to
enforce the Fund's obligation to repurchase the securities and the Fund's use of
the proceeds of the reverse  repurchase  agreement may effectively be restricted
pending such determination.  The staff of the Securities and Exchange Commission
has taken the position that the 1940 Act treats reverse repurchase agreements as
being included in the percentage limit on borrowings imposed on a Fund.

"WHEN ISSUED" SECURITIES
    The Fund may also  purchase and sell  securities  and  currencies  on a when
issued and delayed delivery basis. When issued or delayed delivery  transactions
arise when  securities  or  currencies  are  purchased  or sold by the Fund with
payment  and  delivery  taking  place in the  future in order to secure  what is
considered  to be an  advantageous  price  and  yield to the Fund at the time of
entering into the transaction.  When the Fund engages in when issued and delayed
delivery  transactions,  the Fund relies on the buyer or seller, as the case may
be, to consummate the sale.  Failure to do so may result in the Fund missing the
opportunity  to  obtain a price or yield  considered  to be  advantageous.  When
issued and  delayed  delivery  transactions  may be expected to occur a month or
more before delivery is due. However, no payment or delivery is made by the Fund
until it receives payment or delivery from the other party to the transaction. A
separate  account  of  liquid  assets  equal  to  the  value  of  such  purchase
commitments  will be maintained  until payment is made.  When issued and delayed
delivery  agreements  are  subject  to risks from  changes in value,  based upon
changes in the level of interest rates, currency rates and other market factors,
both  before  and after  delivery.  The Fund does not  accrue any income on such
securities or currencies prior to their delivery. To the extent the Fund engages
in when issued and delayed delivery transactions,  it will do so for the purpose
of acquiring portfolio  securities or currencies  consistent with its investment
objective and policies and not for the purpose of investment leverage.  The Fund
currently does not intend to invest more than 5% of its assets in when issued or
delayed delivery transactions.

OPTIONS TRANSACTIONS
   The Fund may enter into options transactions. Any premium paid by the Fund in
connection  with an option  transaction  may be forfeited if the option  expires
unexercised.

    WRITING COVERED  OPTIONS.  The Fund may write (i.e.,  sell) covered call and
put options.  By writing a call option,  the Fund becomes  obligated  during the
term of the option to deliver the securities  underlying the option upon payment
of the  exercise  price.  By writing a put option,  the Fund  becomes  obligated
during the term of the option to purchase the  securities  underlying the option
at the  exercise  price if the  option  is  exercised.  The Fund  also may write
straddles  (combinations  of  covered  puts and  calls  on the  same  underlying
security).

    The Fund may only write  "covered"  options.  This means that so long as the
Fund is  obligated as the writer of a call  option,  it will own the  underlying
securities  subject  to the  option  or,  in the  case of call  options  on U.S.
Treasury bills, the Fund might own  substantially  similar U.S.  Treasury bills.
The Fund will be considered "covered" with respect to a put option it writes if,
so long as it is  obligated  as the writer of the put option,  it  deposits  and
maintains  with its  custodian in a segregated  account  liquid  assets having a
value equal to or greater than the exercise price of the option.

    The principal reason for writing call or put options is to obtain, through a
receipt of  premiums,  a greater  current  return  than would be realized on the
underlying  securities alone. The Fund receives a premium from writing a call or
put option which it retains whether or not the option is exercised. By writing a
call  option,  the Fund  might  lose the  potential  for gain on the  underlying
security while the option is open,  and by writing a put option,  the Fund might
become  obligated to purchase the underlying  security for more than its current
market price upon exercise.

    PURCHASING  OPTIONS.  The Fund does not  currently  intend to  purchase  put
options.  The Fund may  purchase  call  options  for the  purpose of  offsetting
previously  written call options of the same series.  The Fund also may purchase
call options to fix the interest rates of obligations held by it. If the Fund is
unable to effect a closing purchase  transaction with respect to covered options
it has written,  the Fund will not be able to sell the underlying  securities or
dispose of assets held in a segregated  account until the options  expire or are
exercised.

    An option  position  may be closed  out only in a  secondary  market  for an
option of the same  series.  Although the Fund  generally  will write only those
options for which there appears to be an active  secondary  market,  there is no
assurance that a liquid secondary market will exist for any particular option at
any particular time, and for some options no secondary market may exist. In such
event it might not be possible to effect a closing  transaction  in a particular
option.

    Options  on some  securities  are  relatively  new and it is  impossible  to
predict the amount of trading  interest that will exist in such  options.  There
can be no assurance that viable markets will develop or continue. The failure of
such  markets to  develop  or  continue  could  significantly  impair the Fund's
ability to use such options to achieve its investment objective.

    The Fund  currently  does not intend to invest more than 5% of its assets in
options transactions.

    OPTIONS  TRADING  MARKETS.  Options  which the Fund will trade are generally
listed  on  national  securities  exchanges.  Exchanges  on which  such  options
currently are traded are the Chicago  Board  Options  Exchange and the New York,
American, Pacific and Philadelphia Stock Exchanges (Exchanges).  Options on some
securities may not be listed on any Exchange but traded in the  over-the-counter
market.  Options  traded in the  over-the-counter  market involve the additional
risk that securities  dealers  participating in such transactions  could fail to
meet  their  obligations  to  the  Fund.  The  use  of  options  traded  in  the
over-the-counter  market may be subject to limitations  imposed by certain state
securities  authorities.  In  addition  to  the  limits  on its  use of  options
discussed herein, the Fund is subject to the investment  restrictions  described
in this prospectus and in the statement of additional information.

    The staff of the Securities and Exchange  Commission is of the view that the
premiums which the Fund pays for the purchase of unlisted  options and the value
of securities used to cover unlisted  options written by the Fund are considered
to be invested in illiquid  securities or assets for the purpose of  calculating
whether the Fund is in compliance  with its fundamental  investment  restriction
prohibiting  it  from  investing  more  than  10% of  its  total  assets  in any
combination of illiquid assets and securities.

FUTURES  TRANSACTIONS
    The Fund may enter into currency and other financial  futures  contracts and
write options on such  contracts.  The Fund intends to enter into such contracts
and related options for hedging  purposes.  The Fund will enter into securities,
currencies or index-based futures contracts in order to hedge against changes in
interest  or  exchange  rates  or  securities  prices.  A  futures  contract  on
securities or currencies is an agreement to buy or sell securities or currencies
at a  specified  price  during a  designated  month.  A  futures  contract  on a
securities index does not involve the actual delivery of securities,  but merely
requires  the payment of a cash  settlement  based on changes in the  securities
index. The Fund does not make payment or deliver securities upon entering into a
futures contract.  Instead, it puts down a margin deposit,  which is adjusted to
reflect  changes  in the value of the  contract  and which  continues  until the
contract is terminated.

    The  Fund  may  sell  or  purchase  currency  and  other  financial  futures
contracts.  When a  futures  contract  is sold by the  Fund,  the  value  of the
contract  will  tend to rise  when the  value of the  underlying  securities  or
currencies  declines and to fall when the value of such securities or currencies
increases.  Thus, the Fund sells futures contracts in order to offset a possible
decline in the value of its securities or currencies.  If a futures  contract is
purchased  by the  Fund,  the value of the  contract  will tend to rise when the
value of the underlying  securities or currencies increases and to fall when the
value of such  securities or currencies  declines.  The Fund intends to purchase
futures contracts in order to fix what is believed by Keystone to be a favorable
price  and  rate of  return  for  securities  or  favorable  exchange  rate  for
currencies the Fund intends to purchase.

    The Fund also intends to purchase put and call options on currency and other
financial futures contracts for hedging purposes.  A put option purchased by the
Fund  would  give it the right to assume a  position  as the seller of a futures
contract.  A call option purchased by the Fund would give it the right to assume
a position as the purchaser of a futures contract.  The purchase of an option on
a futures  contract  requires  the Fund to pay a premium.  In  exchange  for the
premium, the Fund becomes entitled to exercise the benefits, if any, provided by
the futures contract, but is not required to take any action under the contract.
If the option cannot be exercised  profitably before it expires, the Fund's loss
will be limited to the amount of the premium and any transaction costs.

    The Fund may enter into closing  purchase and sale  transactions in order to
terminate a futures  contract  and may sell put and call options for the purpose
of closing out its options  positions.  The Fund's ability to enter into closing
transactions  depends on the development  and maintenance of a liquid  secondary
market.  There is no assurance that a liquid secondary market will exist for any
particular  contract or at any  particular  time.  As a result,  there can be no
assurance  that the Fund will be able to enter  into an  offsetting  transaction
with respect to a particular  contract at a particular  time. If the Fund is not
able to enter  into an  offsetting  transaction,  the Fund will  continue  to be
required to maintain  the margin  deposits on the  contract  and to complete the
contract  according to its terms, in which case it would continue to bear market
risk on the transaction.

    Although futures and related options transactions are intended to enable the
Fund to manage  market,  interest  rate or  exchange  rate  risk,  unanticipated
changes in interest  rates,  exchange  rates or market  prices  could  result in
poorer performance than if it had not entered into these  transactions.  Even if
Keystone correctly  predicts interest or exchange rate movements,  a hedge could
be unsuccessful  if changes in the value of the Fund's futures  position did not
correspond to changes in the value of its investments.  This lack of correlation
between the Fund's futures and securities or currencies  positions may be caused
by differences  between the futures and  securities or currencies  markets or by
differences  between the securities or currencies  underlying the Fund's futures
position and the  securities  or  currencies  held by or to be purchased for the
Fund.  Keystone will attempt to minimize these risks through  careful  selection
and monitoring of the Fund's futures and options positions.

    The Fund does not intend to use  futures  transactions  for  speculation  or
leverage.  The Fund has the ability to write options on futures,  but intends to
write such  options only to close out options  purchased  by the Fund.  The Fund
will not change these  policies  without  supplementing  the  information in its
prospectus and statement of additional information.

FOREIGN CURRENCY TRANSACTIONS
    The Fund may invest in obligations denominated in foreign currencies.  Thus,
the value of Fund shares will be affected by changes in exchange  rates.  As one
way of managing  exchange  rate risk,  in addition  to  entering  into  currency
futures  contracts,  the Fund may enter into forward currency exchange contracts
(agreements to purchase or sell currencies at a specified  price and date).  The
exchange rate for the transaction  (the amount of currency the Fund will deliver
or receive  when the contract is  completed)  is fixed when the Fund enters into
the contract.  The Fund usually will enter into these contracts to stabilize the
U.S.  dollar value of a security it has agreed to buy or sell.  The Fund intends
to use these  contracts to hedge the U.S.  dollar value of a security it already
owns,  particularly  if the Fund expects a decrease in the value of the currency
in which the foreign security is denominated.  Although the Fund will attempt to
benefit from using forward  contracts,  the success of its hedging strategy will
depend on Keystone's  ability to predict  accurately  the future  exchange rates
between  foreign  currencies  and the  U.S.  dollar.  The  value  of the  Fund's
investments  denominated  in  foreign  currencies  will  depend on the  relative
strength of those currencies and the U.S.  dollar,  and the Fund may be affected
favorably or unfavorably  by changes in the exchange  rates or exchange  control
regulations  between  foreign  currencies  and the  dollar.  Changes  in foreign
currency  exchange  rates also may affect the value of  dividends  and  interest
earned,  gains and losses  realized on the sale of securities and net investment
income  and  gains,  if any,  to be  distributed  to  shareholders  by the Fund.
Although the Fund does not currently intend to do so, the Fund may also purchase
and sell  options  related  to foreign  currencies.  The Fund does not intend to
enter into foreign currency transactions for speculation or leverage.

                 THE FUND'S OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------
     The Fund's investment objective is to provide shareholders with the highest
possible  current  income,  exempt from federal income taxes,  while  preserving
capital.  The Fund invests  primarily in municipal  bonds but also may invest in
certain other securities as described in the Appendix hereto and the "Additional
Investment Information" section of the Fund's prospectus.

FUNDAMENTAL NATURE OF INVESTMENT OBJECTIVE

     The investment  objective of the Fund is fundamental and may not be changed
without approval of the holders of a majority of the Fund's  outstanding  shares
(which  means the  lesser of (1) 67% of the shares  represented  at a meeting at
which more than 50% of the  outstanding  shares are represented or (2) more than
50% of the outstanding shares).

- --------------------------------------------------------------------------------
                            INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
     None of the  restrictions  enumerated  in  this  paragraph  may be  changed
without a vote of the  holders  of a  majority,  as  defined  in the  Investment
Company Act of 1940 (the "1940 Act"), of the Fund's outstanding shares. The Fund
will not do the following:

     (1) purchase  securities on margin, but the Fund may obtain such short-term
credits  as may be  necessary  for the  clearance  of  purchases  and  sales  of
securities;

     (2) make short sales of securities or maintain a short position,  unless at
all  times  when a short  position  is open it  owns  an  equal  amount  of such
securities or of securities  which without payment of any further  consideration
are convertible  into or  exchangeable  for securities of the same issue as, and
equal in amount to, the securities sold short;

     (3) borrow money,  except that the Fund may (a) borrow money from banks for
emergency or extraordinary  purposes in aggregate amounts up to one-third of its
net assets, and (b) enter into reverse repurchase agreements;

     (4)  pledge,   mortgage  or   hypothecate   its  assets  except  to  secure
indebtedness  permitted by subparagraph (3) above,  with pledged assets to be no
more than 15% of its total assets;  the Fund  understands that pledges in excess
of  approximately  6% of its net assets  would  result in its  inability to sell
additional  shares in one state;  however,  the Fund has no present intention of
exceeding this limit;
<PAGE>
     (5) purchase  any security  other than United  States  ("U.S.")  government
securities  of any issuer if as a result more than 25% of its total assets would
be invested in a single industry,  including  industrial  development bonds from
the same  facility  or  similar  types of  facilities;  governmental  issuers of
municipal  bonds are not  regarded  as members of an  industry  and the Fund may
invest more than 25% of its assets in industrial development bonds;

     (6) purchase any security,  other than U.S. government securities,  if as a
result more than 5% of the Fund's total  assets would be invested in  securities
of the issuer,  or the Fund would hold more than 10% of the voting securities of
the issuer;

     (7) invest for the purpose of exercising  control over or management of any
company;

     (8) invest in securities of other investment companies, except as part of a
merger, consolidation, purchase of assets or similar transaction approved by the
Fund's shareholders;

     (9) purchase or sell  commodities  or  commodity  contracts or real estate,
except  that it may  purchase  and sell  securities  secured by real  estate and
securities of companies which invest in real estate,  and may engage in currency
or other financial futures and related options transactions;

     (10) act as an  underwriter  except to the extent that, in connection  with
the  disposition  of  its  portfolio  investments,  it may  be  deemed  to be an
underwriter under federal securities laws; or purchase  securities which are not
readily marketable except for repurchase agreements;

     (11) purchase or retain securities of an issuer if, to the knowledge of the
Fund, an officer,  Trustee or Director of the Fund or Keystone owns beneficially
more than 1/2 of 1% of the  shares or  securities  of such  issuer  and all such
officers,  Trustees and  Directors  owning more than 1/2 of 1% of such shares or
securities together own more than 5% of such shares or securities;

     (12)  purchase  securities  of any  issuer if the  person  responsible  for
payment,  together  with any  predecessor,  has been in operation  for less than
three years if, as a result,  the aggregate of such investments  would exceed 5%
of the Fund's total assets;  provided,  however, that this restriction shall not
apply to U.S.  government  securities or to any  obligation the payment of which
involves the credit and taxing power of any person authorized to issue municipal
bonds;
<PAGE>
     (13) invest in interests in oil, gas or other mineral exploration
or development programs;

     (14) make loans, except to the extent that the purchase of debt instruments
or  repurchase  agreements  may be  deemed to be  loans;  repurchase  agreements
maturing in more than seven days will not exceed 10% of the Fund's total assets;
and

     (15) purchase securities of foreign issuers.

     The  foregoing  percentage  restrictions  will  apply  at the  time  of the
purchase of a security and shall not be considered  violated unless an excess or
deficiency  occurs or exists  immediately after and as a result of a purchase of
such security.  For the purpose of limitations  (5) and (6), the Fund will treat
each state,  territory and possession of the U.S., the District of Columbia and,
if its assets and  revenues  are  separate  from those of the entity or entities
creating it, each political  subdivision,  agency and instrumentality of any one
(or more,  as in the case of a multistate  authority or agency) of the foregoing
as an  issuer of all  securities  that are  backed  primarily  by its  assets or
revenues;  each company as an issuer of all securities that are backed primarily
by its assets or revenues;  and each of the  foregoing  entities as an issuer of
all securities that it guarantees;  provided,  however,  that for the purpose of
limitation  (6) no entity shall be deemed to be an issuer of a security  that it
guarantees  so long as no more than 10% of the  Fund's  total  assets  (taken at
current  value)  are  invested  in  securities  guaranteed  by  the  entity  and
securities of which it is otherwise deemed to be an issuer.

     The Fund does not  presently  intend  to invest  more than 25% of its total
assets in (1) municipal bonds of a single state and its  subdivisions,  agencies
and  instrumentalities;  of a single territory or possession of the U.S. and its
subdivisions, agencies or instrumentalities;  or of the District of Columbia and
any subdivision,  agency or instrumentality  thereof; or (2) municipal bonds the
payment of which depends on revenues  derived from a single  facility or similar
types of facilities.  Since certain municipal bonds may be related in such a way
that an economic, business or political development or change affecting one such
security could  likewise  affect the other  securities,  a change in this policy
could  result  in  increased   investment  risk,  but  no  change  is  presently
contemplated.  The  Fund  may  invest  more  than  25% of its  total  assets  in
industrial development bonds.
<PAGE>
- --------------------------------------------------------------------------------
                            VALUATION OF SECURITIES
- --------------------------------------------------------------------------------
     The Fund believes that reliable market quotations generally are not readily
available for purposes of valuing municipal bonds. As a result, depending on the
particular  municipal  bonds  owned by the Fund,  it is likely  that most of the
valuations for such bonds will be based upon their fair value  determined  under
procedures  which have been  approved by the Board of Trustees.  Non-tax  exempt
securities  for which market  quotations  are readily  available are valued on a
consistent  basis at that price  quoted  which,  in the  opinion of the Board of
Trustees  or the  person  designated  by the  Board  of  Trustees  to  make  the
determination,  most  nearly  represents  the  market  value  of the  particular
security.  Short-term  investments  which are purchased with maturities of sixty
days or less are valued at amortized  cost  (original  purchase cost as adjusted
for amortization of premium or accretion of discount) which,  when combined with
accrued interest,  approximates market;  short-term investments maturing in more
than sixty days for which market  quotations are readily available are valued at
current  market value;  and short-term  investments  maturing in more than sixty
days when  purchased  which are held on the  sixtieth  day prior to maturity are
valued  at  amortized  cost  (market  value on the  sixtieth  day  adjusted  for
amortization  of premium or accretion of discount)  which,  when  combined  with
accrued interest,  approximates market and which in any case reflects fair value
as  determined  by the Board of Trustees.  All other  investments  are valued at
market value or,  where market  quotations  are not readily  available,  at fair
value as determined  in good faith using methods  prescribed by the Fund's Board
of Trustees.

- --------------------------------------------------------------------------------
                                 SALES CHARGES
- --------------------------------------------------------------------------------
     In order to reimburse the Fund for certain expenses relating to the sale of
its shares (see "Distribution  Plan"), a contingent deferred sales charge may be
imposed at the time of  redemption  of certain Fund shares  within four calendar
years after their purchase.  If imposed, the contingent deferred sales charge is
deducted from the  redemption  proceeds  otherwise  payable to the  shareholder.
Since July 8, 1992, the deferred sales charge  attributable to shares  purchased
prior to January 1, 1992 has been retained by the Fund,  and the deferred  sales
charge  attributable to shares purchased after January 1, 1992 is, to the extent
permitted  by a new rule  adopted  by the  National  Association  of  Securities
Dealers,   Inc.  ("NASD")  paid  to  KDI,  the  Fund's  Principal   Underwriter.
Accordingly,  for the fiscal year ended  December  31, 1993,  the Fund  received
$373,564 and KDI received $482,452 in deferred sales charges.

     The  contingent  deferred  sales  charge is a declining  percentage  of the
lesser of (1) the net asset  value of the shares  redeemed or (2) the total cost
of such  shares.  No  contingent  deferred  sales  charge  is  imposed  when the
shareholder  redeems  amounts  derived  from (1)  increases  in the value of his
account  above the total cost of such shares due to  increases  in the net asset
value per share of the Fund or (2) certain shares with respect to which the Fund
did  not  pay a  commission  on  issuance,  including  shares  acquired  through
reinvestment of dividend income and capital gains  distributions,  or (3) shares
held in all or part of more than four consecutive calendar years.
<PAGE>
     Subject to the  limitations  stated  above,  the Fund  imposes a contingent
deferred  sales  charge  according  to the  following  schedule:  4% of  amounts
redeemed during the calendar year of purchase; 3% of amounts redeemed during the
calendar  year after the year of  purchase;  2% of amounts  redeemed  during the
second  calendar  year after the year of  purchase;  and 1% of amounts  redeemed
during  the third  calendar  year  after  the year of  purchase.  No  contingent
deferred sales charge is imposed on amounts redeemed thereafter.

     The  following  example will  illustrate  the  operation of the  contingent
deferred  sales  charge.  Assume  that an investor  makes a purchase  payment of
$10,000  during the calendar  year 1994 and on a given date in 1995 the value of
the investor's account has grown through investment performance and reinvestment
of distributions  to $12,000.  On such date in 1995 the investor could redeem up
to $2,000 ($12,000 minus $10,000) without incurring a deferred sales charge. If,
on such date, the investor  should redeem $3,000,  a deferred sales charge would
be  imposed  on $1,000 of the  redemption  (the  amount by which the  investor's
account was reduced by the redemption  below the amount of the initial  purchase
payment).  The charge would be imposed at the rate of 3% because the  redemption
is made during the  calendar  year after the calendar  year of  purchase,  for a
total deferred sales charge of $30.

     In determining  whether a contingent  deferred sales charge is payable and,
if so, the  percentage  charge  applicable,  it is assumed  that shares held the
longest are the first to be  redeemed.  There is no  contingent  deferred  sales
charge  imposed on exchanges of shares between the Keystone Group of funds which
have  adopted  distribution  plans  pursuant  to Rule 12b-1  under the 1940 Act.
Moreover, when shares of one such fund have been exchanged for shares of another
such fund,  for purposes of any future  contingent  deferred  sales charge,  the
calendar  year of the  purchase  of the  shares  of the fund  exchanged  into is
assumed to be the year shares tendered for exchange were originally purchased.

     Shares  also  may be sold,  to the  extent  permitted  by  applicable  law,
regulations,  interpretations  or  exemptions,  at net asset  value  without the
imposition of a deferred sales charge upon redemption of shares to (1) officers,
Directors,  Trustees,  full-time employees and sales representatives of Keystone
Management,  Inc.  ("Keystone  Management"),   Keystone  Custodian  Funds,  Inc.
("Keystone"), Keystone Group, Inc. ("Keystone Group"), Harbor Capital Management
Company,  Inc., their  subsidiaries and the Principal  Underwriter who have been
such for not less than ninety days; and (2) the pension and profit-sharing plans
established  by said  companies,  their  subsidiaries  and  affiliates,  for the
benefit of their officers,  Directors,  Trustees,  full-time employees and sales
representatives,  provided all such sales are made upon the written assurance of
the  purchaser  that the purchase is made for  investment  purposes and that the
securities will not be resold except through redemption by the Fund.
<PAGE>

     In addition, no contingent deferred sales charge is imposed on a redemption
of shares of the Fund  purchased by a bank or trust company in a single  account
in the name of such bank or trust company as trustee,  if the initial investment
in shares of the Fund, any Keystone  Custodian  Fund,  Keystone  Precious Metals
Holdings,  Inc.,  Keystone  International Fund Inc.,  Keystone Tax Exempt Trust,
Keystone Liquid Trust and/or any Keystone  America Fund is at least $500,000 and
any  commission  paid by the  Fund  and  such  other  funds  at the time of such
purchase is not more than 1% of the amount invested.

                               DISTRIBUTION PLAN
- --------------------------------------------------------------------------------
     Rule 12b-1 under the 1940 Act  permits  investment  companies,  such as the
Fund to use their assets to bear expenses of  distributing  their shares if they
comply  with  various  conditions,  including  adoption of a  distribution  plan
containing  certain provisions set forth in Rule 12b-1. On January 19, 1983, the
Fund's  Distribution  Plan  described  below was approved by the Fund's Board of
Trustees, including a majority of the Trustees who are not interested persons of
the Fund as defined in the 1940 Act  ("Independent  Trustees")  and the Trustees
who have no direct or indirect  financial  interest in the Distribution  Plan or
any agreement related thereto (the "Rule 12b-1 Trustees" who are the same as the
Independent  Trustees).  On May 27, 1983, the Distribution  Plan was approved by
the Fund's shareholders, and it became effective on June 1, 1983.

     The  Fund's  Distribution  Plan  provides  that the Fund may  expend  up to
0.3125%  quarterly  (approximately  1.25%  annually) of average  daily net asset
value of its shares to pay distribution costs for sales of its shares and to pay
shareholder  service fees. A new rule adopted by the NASD effective July 7, 1993
limits  such annual  expenditures  to 1%, of which 0.75% may be used to pay such
distribution  costs and 0.25% may be used to pay  shareholder  service fees. The
aggregate amount that the Fund may pay for such distribution costs is limited to
6.25% of gross share sales since the inception of the Fund's  Distribution  Plan
plus  interest  at the prime rate plus 1% on unpaid  amounts  thereof  (less any
contingent deferred sales charge paid by shareholders to KDI). The Fund operates
its Distribution Plan in accordance with both the Distribution Plan and the NASD
rule.

     In connection with the Distribution  Plan, Fund shares are offered for sale
at net asset  value  without  any  initial  sales  charge,  and the Fund pays or
accrues to the Principal  Underwriter a commission for each sale.  Specifically,
amounts paid or accrued under the  Distribution  Plan are paid or accrued to the
Fund's Principal Underwriter, currently KDI, as commissions for Fund shares sold
under  the  Distribution  Plan,  all or any  part of  which  commissions  may be
reallowed  by KDI to  others  (dealers).  In  addition,  the  Fund  pays  to the
Principal Underwriter amounts sufficient for the Principal Underwriter to pay to
such others a service fee at a rate of 0.25% per annum of the net asset value of
the shares sold by such others that remain  outstanding on the books of the Fund
for specified  periods.  Such  commissions  and service fees are included in the
Fund's operating expenses.

<PAGE>
     If the Fund is unable to pay KDI a  commission  on a new sale  because  the
annual  maximum  (0.75% of  average  daily net  assets)  has been  reached,  KDI
intends, but is not obligated, to continue to accept new orders for the purchase
of Fund shares and to pay  commissions  and service fees to dealers in excess of
the  amount it  currently  receives  from the  Fund.  While the Fund is under no
contractual  obligation  to reimburse  KDI for advances made by KDI in excess of
the  Distribution  Plan  limitation,  KDI  intends to seek full  payment of such
charges from the Fund (together with interest rate of prime plus one percent) at
such time in the future as, and to the extent that,  payment thereof by the Fund
would be within  permitted  limits.  KDI  currently  intends to seek  payment of
interest  only on such charges paid or accrued by KDI  subsequent  to January 1,
1992. If the Independent Trustees authorize such payments, the effect will be to
extend the period of time during  which the Fund  incurs the  maximum  amount of
costs allowed by the Distribution Plan. The Independent  Trustees have agreed to
reimburse  KDI such  portion of this amount at such future time when the payment
of such  amounts  would  not  cause the Fund to  exceed  the  Distribution  Plan
limitation. If the Distribution Plan is terminated, KDI will ask the Independent
Trustees to take whatever action they deem appropriate  under the  circumstances
with respect to payment of such amounts.

     The total amounts paid by the Fund under the foregoing arrangements may not
exceed the maximum  Distribution Plan limit specified above, and the amounts and
purposes of  expenditures  under the  Distribution  Plan must be reported to the
Fund's Rule 12b-1 Trustees quarterly. The Fund's Rule 12b-1 Trustees may require
or approve changes in the  implementation or operation of the Distribution Plan,
and may also require that total  expenditures by the Fund under the Distribution
Plan be kept  within  limits  lower than the  maximum  amount  permitted  by the
Distribution  Plan as  stated  above.  If such  costs  are  not  limited  by the
Independent Trustees,  such costs could, for some period of time, be higher than
such costs permitted by most other plans presently  adopted by other  investment
companies.

     The  Distribution  Plan may be  terminated  at any time by vote of the Rule
12b-1 Trustees, or by vote of a majority of the outstanding voting securities of
the Fund. Any change in the Distribution Plan that would materially increase the
distribution expenses of the Fund provided for in the Distribution Plan requires
shareholder  approval.  Otherwise,  the Distribution  Plan may be amended by the
Trustees,  including  the  Fund's  Rule  12b-1  Trustees.  The  Fund's  Board of
Trustees,  including  the Fund's  12b-1  Trustees,  most  recently  approved the
continuance of the Fund's Distribution Plan at a meeting held on June 16, 1993.
<PAGE>
     While the  Distribution  Plan is in effect,  the Fund will be  required  to
commit the selection and  nomination of candidates for  Independent  Trustees to
the discretion of the Independent Trustees.

     During  the  fiscal  year  ended  December  31,  1993,  the  Fund  paid KDI
$16,608,165  under  the  Distribution  Plan,  of  which  $4,272,087  represented
repayment of advances.  The amount paid by the Fund under its Distribution Plan,
net of deferred  sales  charges,  was  $16,234,601  (1.06% of the Fund's average
daily net asset  value  during  the  period).  During  the  year,  KDI  retained
$9,241,496 and paid commissions on new sales and maintenance fees to dealers and
others of $7,366,669.

     Whether any expenditure  under the Distribution  Plan is subject to a state
expense  limit will depend upon the nature of the  expenditure  and the terms of
the state law,  regulation or order imposing the limit. Any expenditure  subject
to such a limit will be  included in the Fund's  total  operating  expenses  for
purposes of  determining  compliance  with the expense  limit.  A portion of the
Fund's  Distribution  Plan  expenses  may  be  includable  in the  Fund's  total
operating  expenses for purposes of  determining  compliance  with state expense
limits.

     Commissions  paid on new sales of shares are treated as capital charges and
deferred  sales  charges  received by the Fund are  treated as capital  credits,
respectively, in determining net investment income for tax purposes.

     The Independent  Trustees of the Fund have determined that the sales of the
Fund's shares resulting from payments under the Distribution Plan have benefited
the Fund.

- --------------------------------------------------------------------------------
                             PRINCIPAL UNDERWRITER
- --------------------------------------------------------------------------------

     Pursuant  to  a  Principal   Underwriting   Agreement  (the   "Underwriting
Agreement"),  KDI acts as the Fund's Principal Underwriter.  KDI, located at 200
Berkeley Street,  Boston,  Massachusetts  02116-5034,  is a Delaware corporation
wholly-owned  by  Keystone.  KDI as agent has agreed to use its best  efforts to
find purchasers for the shares.  KDI may retain and employ  representa-tives  to
promote  distribution of the shares and may obtain orders from brokers,  dealers
and others, acting as principals,  for sales of shares to them. The Underwriting
Agreement  provides  that KDI will bear the expense of  preparing,  printing and
distributing  advertising and sales literature and  prospectuses  used by it. In
its capacity as principal  underwriter,  KDI may receive  payments from the Fund
pursuant to the Fund's Distribution Plan.
<PAGE>
     The Underwriting  Agreement  provides that it will remain in effect as long
as  its  terms  and  continuance  are  approved  by a  majority  of  the  Fund's
Independent Trustees at least annually at a meeting called for that purpose, and
if its continuance is approved annually by vote of a majority of Trustees, or by
vote of a majority  of the  outstanding  shares.  The terms of the  Underwriting
Agreement  and such  continuance  were most  recently  approved  by the Board of
Trustees,  including a majority of  Independent  Trustees,  at a meeting held on
June 16, 1993.

     The Underwriting Agreement may be terminated,  without penalty, on 60 days'
written  notice  by  the  Board  of  Trustees  or by a  vote  of a  majority  of
outstanding shares. The Underwriting Agreement will terminate automatically upon
its "assignment" as that term is defined in the 1940 Act.

     From time to time, if in KDI's  judgment it could benefit the sales of Fund
shares, KDI may use its discretion in providing to selected dealers  promotional
materials and selling aids,  including,  but not limited to, personal computers,
related software and Fund data files.

     For the fiscal  years ended  December  31,  1991,  1992 and 1993 KDI earned
commissions  of  $1,089,500,   $7,972,003  and  $4,969,409   (amount  represents
commissions  earned during the fiscal year ended  December 31, 1993 and excludes
recapture by KDI during said fiscal year of  $4,272,087  in advances made during
previous fiscal years),  respectively,  after paying  commissions of $5,637,096,
$7,260,876 and $3,705,342 (amount represents sales commissions only and excludes
$3,661,327 in maintenance  fees paid during the fiscal year),  respectively,  to
retail dealers under the Distribution  Plan. See "Distribution  Plan" section of
this document for additional information.

                              DECLARATION OF TRUST
- --------------------------------------------------------------------------------

     The Fund is a Massachusetts  business trust originally  established under a
Declaration  of Trust  dated  April  12,  1977.  On July 27,  1993,  the  Fund's
Declaration of Trust was amended and restated in its entirety (the  "Declaration
of Trust"). The Fund is similar in most respects to a business corporation.  The
principal  distinction  between  the  Fund  and a  corporation  relates  to  the
shareholder  liability  described  below. A copy of the  Declaration of Trust is
filed  as an  exhibit  to  Post-Effective  No.  24 to  the  Fund's  Registration
Statement of which this  statement of  additional  information  is a part.  This
summary is qualified in its entirety by reference to the Declaration of Trust.

SHAREHOLDER LIABILITY
     Pursuant  to  certain   decisions   of  the  Supreme   Judicial   Court  of
Massachusetts, shareholders of a Massachusetts business trust may, under certain
circumstances,  be held personally liable as partners for the obligations of the
trust. Even if, however, the Fund were held to be a partnership, the possibility
of the  shareholders  incurring  financial  loss for that reason  appears remote
because  the Fund's  Declaration  of Trust  contains  an express  disclaimer  of
shareholder  liability for  obligations  of the Fund and requires that notice of
such  disclaimer be given in each  agreement,  obligation or instrument  entered
into or executed by the Fund or the  Trustees,  and because the  Declaration  of
Trust provides for indemnification out of the trust property for any shareholder
held personally liable for the obligations of the Fund.

VOTING RIGHTS
     Under the terms of the Declaration of Trust, shares are entitled to vote in
the  election of Trustees and on other  matters and no amendment  may be made to
the  Declaration of Trust without the approval of the  shareholders of the Fund.
Shares have non-cumulative  voting rights,  which means that the holders of more
than 50% of the shares voting for the election of Trustees can elect 100% of the
Trustees  to be elected at a meeting,  and,  in such  event,  the holders of the
remaining less than 50% of the shares will not be able to elect any Trustees.

LIMITATION OF TRUSTEES' LIABILITY

     The  Declaration  of Trust provides that a Trustee shall be liable only for
his own willful  defaults  and, if  reasonable  care has been  exercised  in the
selection of officers,  agents,  employees or investment advisers,  shall not be
liable for any neglect or wrongdoing of any such person; provided, however, that
nothing  in the  Declaration  of Trust  shall  protect  a  Trustee  against  any
liability for his willful  misfeasance,  bad faith, gross negligence or reckless
disregard of his duties.

                               INVESTMENT MANAGER
- --------------------------------------------------------------------------------
    Subject to the general supervision of the Fund's Board of Trustees, Keystone
Management,  located at Nevada Financial Center, 3800 Howard Hughes Parkway, Las
Vegas, Nevada 89109, serves as investment manager to the Fund and is responsible
for  the  overall  management  of the  Fund's  business  and  affairs.  Keystone
Management,  organized in 1989, is a wholly-owned subsidiary of Keystone and its
directors and principal executive officers have been affiliated with Keystone, a
seasoned  investment  adviser,  for a number of years.  Keystone Management also
serves as  investment  manager to each of the  Keystone  Custodian  Funds and to
certain other Keystone funds.

    Except as  otherwise  noted  below,  pursuant  to an  Investment  Management
Agreement  with  the  Fund  (the  "Management  Agreement")  and  subject  to the
supervision  of the Fund's Board of Trustees,  Keystone  Management  manages and
administers   the  operation  of  the  Fund,  and  manages  the  investment  and
reinvestment  of the Fund's  assets in  conformity  with the  Fund's  investment
objectives and restrictions.  The Management  Agreement stipulates that Keystone
Management  shall  provide  office  space,  all  necessary  office   facilities,
equipment  and personnel in connection  with its services  under the  Management
Agreement  and pay or reimburse the Fund for the  compensation  of Fund officers
and trustees who are affiliated  with the investment  manager as well as pay all
expenses of Keystone  Management  incurred in connection  with the provisions of
its services. All charges and expenses other than those specifically referred to
as being borne by Keystone Management will be paid by the Fund,  including,  but
not limited  to,  custodian  charges and  expenses;  bookkeeping  and  auditors'
charges and expenses;  transfer agent charges and expenses;  fees of Independent
Trustees; brokerage commissions,  brokers' fees and expenses; issue and transfer
taxes;  costs and expenses  under the  Distribution  Plan;  taxes and trust fees
payable  to  governmental  agencies;  the cost of share  certificates;  fees and
expenses of the registration  and  qualification of the Fund and its shares with
the  Securities  and Exchange  Commission  (sometimes  referred to herein as the
"SEC" or the "Commission") or under state or other securities laws;  expenses of
preparing,   printing  and  mailing   prospectuses,   statements  of  additional
information,  notices,  reports and proxy materials to shareholders of the Fund;
expenses of shareholders' and trustees' meetings;  charges and expenses of legal
counsel for the Fund and for the Trustees of the Fund on matters relating to the
Fund;  charges and expenses of filing  annual and other reports with the SEC and
other  authorities;  and all  extraordinary  charges  and  expenses of the Fund.
Keystone  Management  pays all  charges  and  expenses  relating  to these items
subject to reimbursement by the Fund.

    The  Management  Agreement  permits  Keystone  Management  to enter  into an
agreement with Keystone or another investment  adviser,  under which Keystone or
such other investment adviser, as investment adviser, will provide substantially
all the  services to be provided by  Keystone  Management  under the  Management
Agreement. The Management Agreement also permits Keystone Management to delegate
to Keystone or another  investment  adviser  substantially all of the investment
manager's  rights,  duties  and  obligations  under  the  Management  Agreement.
Keystone Management provides the Fund with certain administrative and management
services,  which  services  include (1)  performing  research and planning  with
respect to (a) the Fund's  qualification as a regulated investment company under
Subchapter  M of the  Internal  Revenue  Code,  (b) tax  treatment of the Fund's
portfolio  investments,  (c) tax treatment of special corporate actions (such as
reorganizations),  (d) state tax matters  affecting the Fund, and (e) the Fund's
distributions  of income and capital gains; and (2) preparing the Fund's federal
and state tax returns;  (3)  providing  services to the Fund's  shareholders  in
connection  with  federal and state  taxation  and  distributions  of income and
capital gains; and (4) storing documents relating to the Fund's activities.

    The Fund pays Keystone  Management  at the end of each calendar  month a fee
for its services consisting of (1) an amount calculated as set forth below:

ANNUAL                                                 AGGREGATE NET
MANAGEMENT                                             ASSET VALUE OF THE
FEE                                INCOME              SHARES OF THE FUND
- --------------------------------------------------------------------------------
                                  2.0% of
                             Gross Dividend and
                              Interest Income
                                    Plus
0.50%     of the first                                  $100,000,000, plus
0.45%     of the next                                   $100,000,000, plus
0.40%     of the next                                   $100,000,000, plus
0.35%     of the next                                   $100,000,000, plus
0.30%     of the next                                   $100,000,000, plus
0.25%     of amounts over                               $500,000,000; and

(2) an amount  equal to  Keystone  Management's  reimbursable  expenses  accrued
during such calendar month.

    As a continuing  condition of  registration  of shares in a state,  Keystone
Management  has agreed to  reimburse  the Fund  annually  for certain  operating
expenses  incurred  by the Fund in excess of certain  percentages  of the Fund's
average daily net assets.  However,  Keystone Management is not required to make
such  reimbursements  to an extent which would result in the Fund's inability to
qualify as a regulated  investment  company  under  provisions  of the  Internal
Revenue Code. This condition may be modified or eliminated in the future.

    The  Management  Agreement  continues  in  effect  from year to year only if
approved  at least  annually  by the Fund's  Board of Trustees or by a vote of a
majority of the  outstanding  shares,  and such renewal has been approved by the
vote of a  majority  of the  Independent  Trustees  cast in  person at a meeting
called for the purpose of voting on such approval.  The Management Agreement may
be terminated, without penalty by the Fund's Board of Trustees or by a vote of a
majority of outstanding  shares on 60 days' written  notice to Keystone,  and by
Keystone on 90 days' written notice to the Fund.  The Management  Agreement will
terminate  automatically  upon its  "assignment"  as that term is defined in the
1940 Act.

    For  additional  discussion  of  fees  paid  to  Keystone  Management,   see
"Investment Adviser" below.

- --------------------------------------------------------------------------------
                               INVESTMENT ADVISER
- --------------------------------------------------------------------------------
    Pursuant to the Management Agreement,  Keystone Management has delegated its
investment   management  functions,   except  for  certain   administrative  and
management  services to be performed in Nevada, to Keystone and has entered into
an Investment Advisory Agreement (the "Advisory Agreement"), with Keystone under
which Keystone provides investment advisory and management services to the Fund.

    Keystone, located at 200 Berkeley Street, Boston,  Massachusetts 02116-5034,
has provided investment advisory and management services to investment companies
and private accounts since it was organized in 1932.  Keystone is a wholly-owned
subsidiary  of  Keystone  Group,  200  Berkeley  Street,  Boston,  Massachusetts
02116-5034.

    Keystone  Group is a  corporation  privately  owned by members of Keystone's
management  and its  affiliates.  The  shares of  Keystone  Group  common  stock
beneficially  owned by  management  are held in a number of voting  trusts,  the
trustees  of which  are  George S.  Bissell,  Albert H.  Elfner,  III,  Roger T.
Wickers,  Edward F. Godfrey and Ralph J. Spuehler,  Jr.  Keystone Group provides
accounting,  bookkeeping,  legal,  personnel and general  corporate  services to
Keystone Management, Keystone, their affiliates and the Keystone Group of Mutual
Funds.

    Pursuant to the Advisory  Agreement,  Keystone  receives for its services an
annual  fee  representing  85%  of  the  management  fee  received  by  Keystone
Management under its Management Agreement.

    Under the terms of the Advisory  Agreement and subject to the supervision of
the Fund's Board of Trustees,  Keystone manages and administers the operation of
the Fund, and manages the investment  and  reinvestment  of the Fund's assets in
conformity with the Fund's investment objectives and restrictions.  The Advisory
Agreement  stipulates  that Keystone shall provide  office space,  all necessary
office facilities, equipment and personnel in connection with its services under
the Advisory  Agreement  and pay or reimburse the Fund for the  compensation  of
Fund officers and trustees who are affiliated  with the  investment  manager and
will pay all expenses of Keystone  incurred in connection  with the provision of
its services. All charges and expenses other than those specifically referred to
as being borne by Keystone will be paid by the Fund, including,  but not limited
to,  custodian  charges and  expenses;  bookkeeping  and  auditors'  charges and
expenses;  transfer agent charges and expenses;  fees of  Independent  Trustees;
brokerage  commissions,  brokers' fees and expenses;  issue and transfer  taxes;
costs and expenses under the Distribution  Plan; taxes and trust fees payable to
governmental agencies; the cost of share certificates,  fees and expenses of the
registration and  qualification of the Fund and its shares with the SEC or under
state or other  securities  laws;  expenses of  preparing,  printing and mailing
prospectuses,  statements of additional information,  notices, reports and proxy
materials to shareholders of the Fund;  expenses of shareholders'  and Trustees'
meetings;  charges  and  expenses  of  legal  counsel  for the  Fund and for the
Trustees of the Fund on matters  relating to the Fund;  charges and  expenses of
filing  annual and other  reports  with the SEC and other  authorities;  and all
extraordinary charges and expenses of the Fund.

    During the fiscal year ended  December 31, 1991, the Fund paid or accrued to
Keystone Management  investment  management fees of $5,070,777 which represented
0.47%  of the  Fund's  average  net  assets.  Of such  amount  paid to  Keystone
Management,  $4,310,160  was paid to Keystone for its  services to the Fund.  In

Management Agreement. For the fiscal year ended December 31, 1991, the total fee

- --------------------------------------------------------------------------------
                                   BROKERAGE
- --------------------------------------------------------------------------------

    It is the  policy  of the  Fund,  in  effecting  transactions  in  portfolio
securities,  to seek best execution of orders at the most favorable prices.  The
determination  of what may constitute  best execution and price in the execution
of a  securities  transaction  by a broker  involves a number of  considerations
including,  without  limitation,  the overall direct net economic  result to the
Fund,  involving both price paid or received and any commissions and other costs
paid, the  efficiency  with which the  transaction  is effected,  the ability to
effect the transaction at all where a large block is involved,  the availability
of the broker to stand ready to execute  potentially  difficult  transactions in
the  future  and the  financial  strength  and  stability  of the  broker.  Such
considerations  are judgmental and are weighed by management in determining  the
overall reasonableness of brokerage commissions paid.

    Subject  to the  foregoing,  a factor in the  selection  of  brokers  is the
receipt of research services,  such as analyses and reports concerning  issuers,
industries,  securities,  economic factors and trends and other  statistical and
factual  information.  Any such  research  and  other  statistical  and  factual
information  provided by brokers to the Fund, Keystone Management or Keystone is
considered  to be in  addition  to and not in lieu of  services  required  to be
performed by Keystone Management under the Management Agreement with the Fund or
Keystone under the Advisory Agreement with Keystone Management.  The cost, value
and specific  application of such information are  indeterminable  and cannot be
practically allocated among the Fund and other clients of Keystone Management or
Keystone who may indirectly  benefit from the availability of such  information.
Similarly,  the Fund may indirectly benefit from information made available as a
result of  transactions  effected for such other  clients.  Under the Management
Agreement  and the  Advisory  Agreement,  Keystone  Management  and Keystone are
permitted  to pay  higher  brokerage  commissions  for  brokerage  and  research
services in  accordance  with Section  28(e) of the  Securities  Exchange Act of
1934. In the event  Keystone  Management and Keystone do follow such a practice,
they will do so on a basis which is fair and equitable to the Fund.

    The Fund's securities transactions are generally principal transactions with
the issuer of the security or with major  underwriters and dealers for municipal
bonds. Accordingly, the Fund does not pay significant brokerage commissions. The
cost  of  securities  purchased  from  underwriters   includes  an  underwriting
commission or concession  and the prices at which  securities are purchased from
and sold to dealers  include a dealer's  mark-up or mark- down.  Purchases  from
underwriters  will  include  the  underwriting   commission  or  concession  and
purchases from dealers  serving as market makers will include the spread between
the bid and asked prices.  Where  transactions are made in the  over-the-counter
market,  the Fund will deal with primary  market  makers  unless more  favorable
prices are otherwise obtainable.

    The Fund may participate,  if and when practicable, in group bidding for the
purchase directly from an issuer of certain  securities for the Fund's portfolio
in order to take advantage of the lower  purchase price  available to members of
such a group.

     Neither  Keystone  Management,  Keystone  nor  the  Fund  intend  to  place
securities  transactions  with any  particular  broker-dealer  or group thereof.
However,  the Fund's Board of Trustees has determined that the Fund may follow a
policy  of  considering  sales  of  shares  as a  factor  in  the  selection  of
broker-dealers to execute portfolio transactions, subject to the requirements of
best execution, including best price, described above.

     The policy of the Fund with respect to brokerage is and will be reviewed by
the Fund's Board of Trustees from time to time.  Because of the  possibility  of
further regulatory developments affecting the securities exchanges and brokerage
practices  generally,  the  foregoing  practices  may be  changed,  modified  or
eliminated.

     Investment  decisions  for the  Fund  are made  independently  by  Keystone
Management  or Keystone  from those of the other funds and  investment  accounts
managed by Keystone  Management or Keystone.  It may frequently develop that the
same  investment  decision  is  made  for  more  than  one  fund.   Simultaneous
transactions  are  inevitable  when  the  same  security  is  suitable  for  the
investment  objective  of more  than  one  account.  When  two or more  funds or
accounts  are  engaged  in the  purchase  or  sale  of the  same  security,  the
transactions  are allocated as to amount in  accordance  with a formula which is
equitable  to each fund or  account.  It is  recognized  that in some cases this
system could have a detrimental effect on the price or volume of the security as
far as the Fund is concerned.  In other cases,  however, it is believed that the
ability of the Fund to  participate in volume  transactions  will produce better
executions for the Fund.

     For the fiscal years ended  December 31, 1991,  1992 and 1993, the Fund did
not pay any brokerage commissions for securities transactions.

     In no instance are portfolio  securities purchased from or sold to Keystone
Management,  Keystone, KDI or any of their affiliated persons, as defined in the
1940 Act and rules and regulations issued thereunder.

- --------------------------------------------------------------------------------
                 STANDARDIZED TOTAL RETURN AND YIELD QUOTATIONS
- --------------------------------------------------------------------------------
    Total return quotations for the Fund as they may appear from time to time in
advertisements  are calculated by finding the average annual compounded rates of
return  over  the  one,  five  and ten year  periods  on a  hypothetical  $1,000
investment  that  would  equate  the  initial  amount  invested  to  the  ending
redeemable value. To the initial  investment all dividends and distributions are
added, and all recurring fees charged to all shareholder  accounts are deducted.
The ending redeemable value assumes a complete redemption at the end of the one,
five or ten year periods.

     The  total  returns  of the  Fund for the one,  five  and ten  years  ended
December  31, 1993 were 7.15%  (including  contingent  deferred  sales  charge),
54.15% and  163.42%,  respectively.  The average  annual rates of return for the
five and ten year  periods  ended  December  31,  1993 were  9.04%  and  10.17%,
respectively.

     Current  yield  quotations  as  they  may  appear  from  time  to  time  in
advertisements will consist of a quotation based on a 30-day period ended on the
date of the most recent balance sheet of the Portfolio, computed by dividing the
net investment income per share earned during the period by the maximum offering
price per share on the last day of the base  period.  The current  yield for the
30-day period ended December 31, 1993 was 4.53%.

    Tax equivalent  yield is, in general,  the current yield divided by a factor
equal to one minus a stated  income  tax rate and  reflects  the yield a taxable
investment  would have to achieve in order to equal on an after  tax-basis a tax
exempt yield.  The tax equivalent yield for the 30-day period ended December 31,
1993 was 6.29%.

    Any  given  yield  or  total  return  quotation  should  not  be  considered
representative of the Fund's yield or total return for any future period.

- --------------------------------------------------------------------------------

                                MUNICIPAL BONDS
    Municipal bonds include debt obligations  issued by or on behalf of a state,
a territory,  or a possession of the United States,  the District of Columbia or
any  political  subdivision,  agency or  instrumentality  thereof (for  example,
counties, cities, towns, villages,  districts,  authorities) to obtain funds for
various public  purposes,  including the  construction of a wide range of public
facilities  such  as  airports,  bridges,  highways,  housing,  hospitals,  mass
transportation,  schools,  streets  and  water  and sewer  works.  Other  public
purposes  for which  municipal  bonds may be issued  include  the  refunding  of
outstanding  obligations,  obtaining  funds for general  operating  expenses and
obtaining funds to lend to public or private  institutions  for the construction
of facilities such as educational, hospital and housing facilities. In addition,
certain types of industrial  development  bonds have been or may be issued by or
on behalf of public authorities to finance certain privately operated facilities
and certain local  facilities  for water supply,  gas,  electricity or sewage or
solid waste  disposal.  Such  obligations are included within the term municipal
bonds if the interest paid thereon  qualifies as exempt from federal income tax.
The  income of certain  types of  industrial  development  bonds used to finance
certain  privately  operated  facilities  (qualified  "private  activity" bonds)
issued after August 7, 1986, while exempt from federal income tax, is includable
for purposes of the calculation of the  altnerative  minimum tax. Other types of
industrial   development   bonds,  the  proceeds  of  which  are  used  for  the
construction,  equipment, repair or improvement of privately operated industrial
or commercial  facilities,  may constitute municipal bonds, although the current
federal tax laws place substantial limitations on the size of such issues.

    The  two  principal   classifications   of  municipal   bonds  are  "general
obligation" and limited obligation or "revenue" bonds.  General obligation bonds
are obligations  involving the credit of an issuer  possessing  taxing power and
are payable from the  issuer's  general  unrestricted  revenues and not from any
particular  fund or revenue  source.  Their  payment  may be  dependent  upon an
appropriation   by  the  issuer's   legislative  body  and  may  be  subject  to
quantitative  limitations on the issuer's taxing power. The  characteristics and
methods of  enforcement  of general  obligation  bonds vary according to the law
applicable to the  particular  issuer.  Limited  obligation or revenue bonds are
payable  only from the revenues  derived from a particular  facility or class of
facilities  or, in some cases,  from the  proceeds of a special  excise or other
specific  revenue  source,  such  as  the  user  of  the  facility.   Industrial
development  bonds which are municipal bonds are in most cases revenue bonds and
generally  are not payable  from the  unrestricted  revenues of the issuer.  The
credit  quality of  industrial  development  revenue  bonds is usually  directly
related to the credit  standing  of the owner or user of the  facilities.  There
are, of course,  variations  in the security of municipal  bonds,  both within a
particular  classification  and between  classifications,  depending on numerous
factors.

    The  yields on  municipal  bonds are  dependent  on a  variety  of  factors,
including  general  money  market  conditions,  the  financial  condition of the
issuer,  general  conditions of the municipal bond market,  size of a particular
offering, the maturity of the obligation and rating of the issue. The ratings of
Moody's Investors  Service,  Inc.  ("Moody's") and Standard & Poor's Corporation
("S&P"),  as described below,  represent their opinions as to the quality of the
municipal bonds which they undertake to rate. It should be emphasized,  however,
that   ratings  are  general  and  are  not   absolute   standards  of  quality.
Consequently,  municipal bonds with the same maturity,  interest rate and rating
may have  different  yields  while  municipal  bonds of the  same  maturity  and
interest rate with different  ratings may have the same yield. It should also be
noted  that  the  standards  of  disclosure  applicable  to and  the  amount  of
information  relating to the financial  condition of issuers of municipal  bonds
are not as extensive as those generally relating to corporations.

    Subsequent to its purchase by the Fund, an issue of municipal bonds or other
investment  may cease to be rated or its rating may be reduced below the minimum
rating required for purchase by the Fund. Neither event requires the elimination
of such obligation from the Fund's portfolio, but Keystone will consider such an
event in its  determination  of whether  the Fund  should  continue to hold such
obligation in its portfolio.

    The ability of the Fund to achieve its  investment  objective  is  dependent
upon the  continuing  ability  of  issuers  of  municipal  bonds  to meet  their
obligations  to pay interest and principal  when due.  Obligations of issuers of
municipal  bonds,  including  municipal bonds issued by them, are subject to the
provisions of  bankruptcy,  insolvency  and other laws  affecting the rights and
remedies of  creditors,  such as the federal  Bankruptcy  Act, and laws, if any,
which may be enacted by Congress or state  legislatures  extending  the time for
payment of principal or interest,  or both, or imposing other  constraints  upon
enforcement of such obligations.  There is also the possibility that as a result
of  litigation  or other  conditions,  the power or  ability  of any one or more
issuers to pay,  when due,  principal of and interest on its or their  municipal
bonds may be materially affected.  In addition the market for municipal bonds is
often  thin  and can be  temporarily  affected  by  large  purchases  and  sales
including those by the Fund.

    From time to time,  proposals have been  introduced  before Congress for the
purpose of  restricting  or  eliminating  the federal  income tax  exemption for
interest on municipal bonds, and similar proposals may well be introduced in the
future. If such a proposal were enacted, the availability of municipal bonds for
investment by the Fund and the value of the Fund's portfolio could be materially
affected,  in which event the Fund would reevaluate its investment objective and
policies and consider changes in the structure of the Fund or dissolution.

DESCRIPTION OF BOND RATINGS
    The Tax  Reform Act of 1986 made  significant  changes  in the  federal  tax
status of certain  obligations which were previously fully federally tax exempt.
As a result,  three categories of such  obligations  issued after August 7, 1986
now exist:  (1) "public purpose" bonds, the income of which remains fully exempt
from federal income tax, (2) qualified "private activity" industrial development
bonds,  the income of which,  while exempt from federal income tax under section
103 of the Internal  Revenue Code of 1954 as amended (Code) is includable in the
calculation of the federal  alternative  minimum tax, and (3) "private activity"
(private  purpose) bonds,  the income of which is not exempt from federal income
tax. The Fund will not invest in private activity  (private purpose) bonds, and,
except as  described  under  "Other  Eligible  Securities",  will not  invest in
qualified "private activity" industrial development bonds.

                      CORPORATE AND MUNICIPAL BOND RATINGS
S&P CORPORATE AND MUNICIPAL BOND RATINGS
A. MUNICIPAL NOTES
    An S&P note rating  reflects the liquidity  concerns and market access risks
unique to notes. Notes due in 3 years or less will likely receive a note rating.
Notes maturing  beyond 3 years will most likely receive a long term debt rating.
The following criteria are used in making that assessment:

    a.  Amortization  schedule (the larger the final maturity  relative to other
maturities the more likely it will be treated as a note), and

    b. Source of payment (the more  dependent the issue is on the market for its
refinancing, the more likely it will be treated as a note).

         Note ratings are as follows:

         1. SP-1 Very strong or strong  capacity to pay  principal and interest.
Those issues determined to possess  overwhelming safety  characteristics will be
given a plus (+) designation.

         2. SP-2 Satisfactory capacity to pay principal and interest.

         3. SP-3 Speculative capacity to pay principal and interest.

B.  TAX EXEMPT DEMAND BONDS
    S&P assigns "dual" ratings to all long-term debt issues that have as part of
their provisions a demand or double feature.

    The first rating  addresses  the  likelihood  of repayment of principal  and
interest as due, and the second rating  addresses only the demand  feature.  The
long-term  debt  rating  symbols  are used for  bonds to  denote  the  long-term
maturity  and the  commercial  paper  rating  symbols are used to denote the put
option (for example,  "AAA/A-1+"). For the newer "demand notes," S&P note rating
symbols,  combined with the  commercial  paper  symbols,  are used (for example,
"SP-1+/A-1+" ).

C.   CORPORATE AND MUNICIPAL BOND RATINGS
    An S&P  corporate or municipal  bond rating is a current  assessment  of the
creditworthiness  of an  obligor,  including  obligors  outside  the U.S.,  with
respect to a specific  obligation.  This assessment may take into  consideration
obligors such as guarantors,  insurers, or lessees. Ratings of foreign obligors
do not take into  account  currency  exchange  and  related  uncertainties.  The
ratings are based on current information  furnished by the issuer or obtained by
S&P from other sources it considers reliable.

    The ratings are based, in varying degrees, on the following considerations:

    a.  Likelihood  of default - capacity and  willingness  of the obligor as to
        the timely  payment of interest and repayment of principal in accordance
        with the terms of the obligation;

    b.  Nature of and provisions of the obligation; and

    c.  Protection  afforded by and relative  position of the  obligation in the
        event of bankruptcy  reorganization  or other arrangement under the laws
        of bankruptcy and other laws affecting creditors' rights.

    PLUS (+) OR MINUS  (-):  To  provide  more  detailed  indications  of credit
quality, ratings FROM "AA" TO "BBB" may be modified by the addition of a plus or
minus sign to show relative standing within the major rating categories.

    A  provisional  rating is sometimes  used by S&P. It assumes the  successful
completion of the project  being  financed by the debt being rated and indicates
that payment of debt service  requirements is largely or entirely dependent upon
the successful and timely completion of the project. This rating, however, while
addressing  credit  quality  subsequent to  completion of the project,  makes no
comment on the  likelihood  of, or the risk of default  upon  failure  of,  such
completion.

Bond ratings are as follows:

    1. AAA - Debt rated AAA has the highest rating assigned by S&P.  Capacity to
pay interest and repay principal is extremely strong.

    2. AA - Debt rated AA has a very strong  capacity to pay  interest and repay
principal and differs from the higher rated issues only in small degree.

    3. A -  Debt  rated  A has a  strong  capacity  to pay  interest  and  repay
principal  although it is somewhat more  susceptible  to the adverse  effects of
changes in  circumstances  and  economic  conditions  than debt in higher  rated
categories.

    4. BBB - Debt rated BBB is regarded  as having an  adequate  capacity to pay
interest and repay principal.  Whereas it normally exhibits adequate  protection
parameters,  adverse  economic  conditions  or changing  circumstances  are more
likely to lead to a weakened  capacity to pay interest and repay  principal  for
debt in this category than in higher rated categories.

MOODY'S CORPORATE AND MUNICIPAL BOND RATINGS
    Moody's ratings are as follows:

         1.  Aaa - Bonds  which  are  rated  Aaa are  judged  to be of the  best
quality.  They carry the smallest  degree of  investment  risk and are generally
referred to as "gilt-edge".  Interest payments are protected by a large or by an
exceptionally   stable  margin  and  principal  is  secure.  While  the  various
protective  elements are likely to change, such changes as can be visualized are
most unlikely to impair the fundamentally strong position of such issues.

    2. Aa - Bonds  which are rated Aa are  judged to be of high  quality  by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than the best bonds  because  margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements  may be of greater  amplitude  or there may be other  elements  present
which make the long-term risks appear somewhat larger than in Aaa- securities.

    3. A - Bonds which are rated A possess many favorable investment  attributes
and are to be  considered  as upper medium  grade  obligations.  Factors  giving
security to principal and interest are  considered  adequate but elements may be
present which suggest a susceptibility to impairment sometime in the future.

    4.  Baa -  Bonds  which  are  rated  Baa  are  considered  as  medium  grade
obligations,  i.e.,  they are  neither  highly  protected  nor  poorly  secured.
Interest  payments and principal  security  appear  adequate for the present but
certain  protective  elements  may  be  lacking  or  may  be  characteristically
unreliable over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.

     Moody's  applies  numerical  modifiers,  1, 2 and 3 in each generic  rating
classification  from Aa through Baa in its  corporate  bond rating  system.  The
modifier 1 indicates  that the  security  ranks in the higher end of its generic
rating category;  the modifier 2 indicates a mid-range ranking; and the modifier
3  indicates  that  the  issue  ranks in the  lower  end of its  generic  rating
category.

    CON.  (---) -  Municipal  bonds  for  which the  security  depends  upon the
completion  of  some  act  or  the  fulfillment  of  some  condition  are  rated
conditionally.  These are bonds  secured  by (a)  earnings  of  projects  under
construction,  (b) earnings of projects unseasoned in operation experience,  (c)
rentals which begin when facilities are completed, or (d) payments to which some
other limiting condition attaches.  Parenthetical rating denotes probable credit
stature upon completion of construction or elimination of basis of condition.

    Those  municipal  bonds in the Aa, A, AND Baa groups which Moody's  believes
possess the strongest investment  attributes are designated by the symbols Aa 1,
A 1, AND Baa 1.

                            MONEY MARKET INSTRUMENTS
    The Fund's investments in commercial paper are limited to those rated A-1 by
S&P,  Prime-1 by Moody's,  or F-1 by Fitch  Investors  Service,  Inc.("Fitch's")
These ratings and other money market instruments are described as follows:

COMMERCIAL PAPER RATINGS
    Commercial  paper  rated  A-1  by S&P  has  the  following  characteristics:
Liquidity ratios are adequate to meet cash requirements.  The issuer's long-term
senior debt is rated "A" or better,  although in some cases "BBB" credits may be
allowed. The issuer has access to at least two additional channels of borrowing.
Basic  earnings  and cash flow  have an upward  trend  with  allowance  made for
unusual circumstances.  Typically, the issuer's industry is well established and
the issuer has a strong position within the industry.

    Commercial paper rated A-2 by S&P has the same characteristics as that rated
A-1 except that the relative degree of safety is not as overwhelming.

    Commercial  paper rated A-3 has a satisfactory  capacity for timely payment.
However,  it is somewhat more  vulnerable  to the adverse  effects of changes in
circumstances than obligations rated A-1 or A-2.

    The rating  Prime-1 is the  highest  commercial  paper  rating  assigned  by
Moody's.  Among the factors  considered by Moody's in assigning  ratings are the
following:  (1)  evaluation  of the  management  of  the  issuer;  (2)  economic
evaluation  of  the  issuer's   industry  or  industries  and  an  appraisal  of
speculative-type risks which may be inherent in certain areas; (3) evaluation of
the issuer's  products in relation to competition and customer  acceptance;  (4)
liquidity;  (5) amount and quality of long-term debt; (6) trend of earnings over
a period of ten  years;  (7)  financial  strength  of a parent  company  and the
relationships which exist with the issuer; and (8) recognition by the management
of  obligations  which  may be  present  or may  arise  as a  result  of  public
preparations  to meet such  obligations.  Relative  strength  or weakness of the
above  factors  determines  how the  issuer's  commercial  paper is rated within
various categories.

    Commercial paper rated Prime-2  by Moody's is considered somewhat lower than
the best  commercial  paper because margins of protection may not be as large or
because  fluctuations of protective  elements over the near or intermediate term
may be of greater amplitude.

UNITED STATES GOVERNMENT SECURITIES
    Securities  issued or guaranteed by the United States  Government  include a
variety  of  Treasury  securities  that  differ  only in their  interest  rates,
maturities and dates of issuance.  Treasury bills have maturities of one year or
less.  Treasury  notes have  maturities  of one to ten years and Treasury  bonds
generally have maturities of greater than ten years at the date of issuance.

    Securities  issued or  guaranteed  by the United  States  Government  or its
agencies or  instrumentalities  include direct  obligations of the United States
Treasury  and   securities   issued  or  guaranteed   by  the  Federal   Housing
Administration,  Farmers Home Adminis tration,  Export-Import Bank of the United
States, Small Business Administration, Government National Mortgage Association,
General Services  Administration,  Central Bank for  Cooperatives,  Federal Home
Loan Banks,  Federal Loan  Mortgage  Corporation,  Federal  Intermediate  Credit
Banks,  Federal  Land  Banks,  Maritime  Administration,  The  Tennessee  Valley
Authority,  District of Columbia  Armory  Board and  Federal  National  Mortgage
Association.

    Some obligations of United States Government agencies and instrumentalities,
such as Treasury bills and Government National Mortgage Association pass-through
certificates,  are supported by the full faith and credit of the United  States;
others,  such as  securities  of Federal  Home Loan  Banks,  by the right of the
issuer to borrow from the Treasury;  still  others,  such as bonds issued by the
Federal National Mortgage Association, a private corporation, are supported only
by the credit of the  instrumentality.  Because the United States  Government is
not obligated by law to provide support to an instrumentality  it sponsors,  the
Fund will invest in the securities issued by such an  instrumentality  only when
Keystone  determines  that the credit risk with  respect to the  instrumentality
does not make its securities  unsuitable  investments.  United States Government
securities will not include international agencies or instrumentalities in which
the United States  Government,  its agencies or  instrumentalities  participate,
such  as the  World  Bank,  the  Asian  Development  Bank  or the  InterAmerican
Development   Bank,  or  issues  insured  by  the  Federal   Deposit   Insurance
Corporation.

CERTIFICATES OF DEPOSITS

    Certificates  of deposit are  receipts  issued by a bank in exchange for the
deposit of funds. The issuer agrees to pay the amount deposited plus interest to
the  bearer  of the  receipt  on the  date  specified  on the  certificate.  The
certificate usually can be traded in the secondary market prior to maturity.

    Certificates   of  deposit  will  be  limited  to  U.S.   dollar-denominated
certificates  of United States banks,  including  their branches  abroad) and of
U.S. branches of foreign banks,  which are members of the Federal Reserve System
or the Federal Deposit  Insurance  Corporation,  and have at least $1 billion in
deposits as of the date of their most recently published financial statements.

    The Fund  will not  acquire  time  deposits  or  obligations  issued  by the
International  Bank for  Reconstruction  and Development,  the Asian Development
Bank or the  Inter-American  Development Bank.  Additionally,  the Fund does not
currently  intend to  purchase  foreign  securities  (except to the extent  that
certificates of deposit of foreign  branches of U.S. banks may be deemed foreign
securities) or purchase  certificates of deposit,  bankers' acceptances or other
similar obligations issued by foreign banks.

BANKERS' ACCEPTANCES
    Bankers'  acceptances  typically arise from short-term  credit  arrangements
designed  to  enable   businesses   to  obtain   funds  to  finance   commercial
transactions.  Generally,  an  acceptance  is a time draft drawn on a bank by an
exporter or an importer to obtain a stated  amount of funds to pay for  specific
merchandise.  The  draft  is  then  "accepted"  by the  bank  that,  in  effect,
unconditionally  guarantees  to pay the  face  value  of the  instrument  on its
maturity  date.  The  acceptance  may then be held by the  accepting  bank as an
earning  asset or it may be sold in the  secondary  market at the going  rate of
discount for a specific maturity.  Although maturities for acceptances can be as
long as 270  days,  most  acceptances  have  maturities  of six  months or less.
Bankers'  acceptances  acquired  by the Fund  must have  been  accepted  by U.S.
commercial banks,  including foreign branches of U.S.  commercial banks,  having
total  deposits  at the time of  purchase  in excess of $1  billion  and must be
payable in U.S. dollars.

                        OPTIONS TRANSACTIONS
    The Fund may enter into options  transactions.  Any premium paid by the Fund
in connection with an option  transaction may be forfeited if the option expires
unexercised.

    WRITING  COVERED  OPTIONS.  The Fund writes only  covered  options.  Options
written by the Fund will  normally have  expiration  dates of not more than nine
months from the date  written.  The exercise  price of the options may be below,
equal to, or above the current market values of the underlying securities at the
times the options are written.

    Unless the option  has been  exercised,  the Fund may close out an option it
has written by effecting a closing purchase transaction, whereby it purchases an
option covering the same underlying  security and having the same exercise price
and  expiration  date ("of the same  series") as the one it has written.  If the
Fund  desires  to sell a  particular  security  on which it has  written  a call
option,  it will effect a closing purchase  transaction prior to or concurrently
with the sale of the  security.  If the  Fund is able to  enter  into a  closing
purchase  transaction,  the Fund  will  realize  a profit  (or  loss)  from such
transaction  if the cost of such  transaction is less (or more) than the premium
received from the writing of the option.

    An option  position  may be closed  out only in a  secondary  market  for an
option of the same  series.  Although the Fund will  generally  write only those
options for which there appears to be an active  secondary  market,  there is no
assurance that a liquid secondary market will exist for any particular option at
any particular time, and for some options no secondary market may exist. In such
event able to effect a closing purchase transaction, it will not be able to sell
the underlying securities until the option expires or it delivers the underlying
securities upon exercise.

    Because the Fund intends to qualify as a regulated  investment company under
the Internal  Revenue Code,  the extent to which the Fund may write covered call
options and enter into so-called "straddle"  transactions involving put and call
options may be limited.

    Many options are traded on registered securities  exchanges.  Options traded
on such  exchanges  are issued by the  Options  Clearing  Corporation  (OCC),  a
clearing corporation which assumes  responsibility for the completion of options
transactions.

    PURCHASING PUT AND CALL OPTIONS.  The Fund can close out a put option it has
purchased  by effecting a closing sale  transaction;  for example,  the Fund may
close out a put option it has purchased by selling a put option.  If, however, a
secondary  market  does not exist at a time the Fund  wishes to effect a closing
sale  transaction,  the Fund will have to  exercise  the option to  realize  any
profit.  In  addition,  in a  transaction  in which  the  Fund  does not own the
security  underlying a put option it has purchased,  the Fund would be required,
in the absence of a secondary market, to purchase the underlying security before
it could  exercise  the  option.  In each such  instance,  the Fund would  incur
additional transaction costs.

    The Fund may purchase call options for the purpose of offsetting  previously
written call options of the same series. The Fund also may purchase call options
to fix the interest rates of obligations held by it.

    The Fund will not  purchase a put  option if, as a result of such  purchase,
more  than 10% of its  total  assets  would be  invested  in  premiums  for such
options.  The Fund's  ability to purchase put and call options may be limited by
the  Internal  Revenue  Code's  requirements  for  qualification  as a regulated
investment company.

OPTION WRITING AND RELATED RISKS
    The Fund may write  covered  call and put  options.  A call option gives the
purchaser of the option the right to buy, and the writer the obligation to sell,
the  underlying  security  at the  exercise  price  during  the  option  period.
Conversely,  a put option gives the purchaser the right to sell,  and the writer
the obligation to buy, the underlying  security at the exercise price during the
option period.

    So long  as the  obligation  of the  writer  continues,  the  writer  may be
assigned an exercise  notice by the  broker-dealer  through  whom the option was
sold. The exercise notice would require the writer to deliver,  in the case of a
call, or take delivery of, in the case of a put, the underlying security against
payment of the exercise price. This obligation terminates upon expiration of the
option,  or at such  earlier  time as the  writer  effects  a  closing  purchase
transaction  by  purchasing  an option of the same series as the one  previously
sold.  Once an option has been  exercised,  the writer may not execute a closing
purchase  transaction.  For  options  traded on  national  securities  exchanges
(Exchanges),  to secure the obligation to deliver the underlying security in the
case of a call option, the writer of the option is required to deposit in escrow
the underlying security or other assets in accordance with the rules of the OCC,
an  institution  created to  interpose  itself  between  buyers  and  sellers of
options.  Technically, the OCC assumes the order side of every purchase and sale
transaction  on an  Exchange  and,  by doing  so,  gives  its  guarantee  to the
transaction.

    The  principal  reason for writing  options on a securities  portfolio is to
attempt to realize, through the receipt of premiums, a greater return than would
be realized on the underlying  securities alone. In return for the premium,  the
covered call option writer has given up the  opportunity for profit from a price
increase in the  underlying  security  above the  exercise  price so long as the
option  remains  open,  but  retains  the risk of loss  should  the price of the
security decline.  Conversely, the put option writer gains a profit, in the form
of a premium,  so long as the price of the underlying security remains above the
exercise  price,  but assumes an obligation to purchase the underlying  security
from the buyer of the put option at the exercise price, even though the price of
the security may fall below the  exercise  price,  at any time during the option
period.  If an option  expires,  the writer realizes a gain in the amount of the
premium.  Such a gain may, in the case of a covered call option,  be offset by a
decline in the market value of the underlying security during the option period.
If a call option is exercised,  the writer realizes a gain or loss from the sale
of the  underlying  security.  If a put option is  exercised,  the  writer  must
fulfill his  obligation  to purchase  the  underlying  security at the  exercise
price,  which  will  usually  exceed  the then  market  value of the  underlying
security.  In addition,  the premium paid for the put effectively  increases the
cost of the underlying  security,  thus reducing the yield  otherwise  available
from such securities.

    Because the Fund can write only covered  options,  it may at times be unable
to write additional  options unless it sells a portion of its portfolio holdings
to obtain new securities against which it can write options.  This may result in
higher portfolio turnover and correspondingly  greater brokerage commissions and
other transaction costs.

    To the extent  that a secondary  market is  available,  the  covered  option
writer  may close out  options  it has  written  prior to the  assignment  of an
exercise notice by purchasing,  in a closing purchase transaction,  an option of
the same series as the option previously  written. If the cost of such a closing
purchase  plus  transaction  costs is greater  than the  premium  received  upon
writing the original option, the writer will incur a loss in the transaction.

OPTIONS TRADING MARKETS
    Options  which  the  Fund  will  trade  are  generally  listed  on  national
securities  exchanges.  Exchanges on which such options currently are traded are
the Chicago  Board Options  Exchange and the New York,  American,  Pacific,  and
Philadelphia Stock Exchanges (Exchanges).  Options on some securities may not be
listed on any Exchange but traded in the over the counter market. Options traded
in the over the counter  market  involve  the  additional  risk that  securities
dealers  participating in such transactions would fail to meet their obligations
to the Fund.  The use of options  traded in the over the  counter  market may be
subject to  limitations  imposed by certain  state  securities  authorities.  In
addition  to the  limits on its use of  options  discussed  herein,  the Fund is
subject to the investment restrictions described in the prospectus and statement
of additional information.

    The staff of the Securities and Exchange Commission  (Commission)  currently
is of the view  that  the  premiums  which  the Fund  pays for the  purchase  of
unlisted  options,  and the value of securities  used to cover unlisted  options
written by the Fund are  considered  to be invested in  illiquid  securities  or
assets for the purpose of calculating whether the Fund is in compliance with its
fundamental investment  restriction  prohibiting it from investing more than 10%
of its total  assets  (taken at current  value) in any  combination  of illiquid
assets and  securities.  The Fund intends to request that the  Commission  staff
reconsider  its current view. It is the intention of the Fund to comply with the
staff's current position and the outcome of such reconsideration.

SPECIAL CONSIDERATIONS APPLICABLE TO OPTIONS
    ON TREASURY BONDS AND NOTES. Because trading interest in U.S. Treasury bonds
and notes  tends to center on most  recently  auctioned  issues,  new  series of
options with expirations to replace  expiring options on particular  issues will
not be  introduced  indefinitely.  Instead,  the  expirations  introduced at the
commencement  of options  trading on a  particular  issue will be allowed to run
their course,  with the possible addition of a limited number of new expirations
as the original  ones expire.  Options  trading on each series of bonds or notes
will thus be phased out as new options are listed on the more recent issues, and
a full range of  expiration  dates will not  ordinarily  be available  for every
series on which options are traded.

    ON TREASURY BILLS.  Because the deliverable U.S.  Treasury bill changes from
week to week,  writers of U.S.  Treasury  bills call options  cannot  provide in
advance for their  potential  exercise  settlement  obligations by acquiring and
holding the underlying  security.  However, if the Fund holds a long position in
U.S. Treasury bills with a principal amount corresponding to the option contract
size, the Fund may be hedged from a risk standpoint.  In addition, the Fund will
maintain in a  segregated  account  with its  Custodian  able in the event of an
assignment  of an  exercise  notice to ensure  that it can meet its open  option
obligations.

    ON GNMA CERTIFICATES.  Options on GNMA certificates are not currently traded
on any  Exchange.  However,  the Fund may purchase and write such options in the
over the counter market, or should they commence trading, on any Exchange.

    Since the remaining  principal  balance of GNMA  certificates  declines each
month as a result of mortgage payments,  the Fund, as a writer of a covered GNMA
call holding GNMA certificates as "cover" to satisfy its delivery  obligation in
the  event  of  assignment  of an  exercise  notice,  may  find  that  its  GNMA
certificates no longer have a sufficient  remaining  principal  balance for this
purpose.  Should  this  occur,  the Fund  will  enter  into a  closing  purchase
transaction or will purchase additional GNMA certificates from the same pool (if
obtainable)  or  replacement  GNMA  certificates  in the cash market in order to
remain covered.

    A GNMA  certificate  held by the Fund to cover an option position in any but
the nearest  expiration  month may cease to present  cover for the option in the
event of a decline  in the GNMA  coupon  rate at which new pools are  originated
under the FHA/VA loan  ceiling in effect at any given  time.  Should this occur,
the Fund will no longer  be  covered,  and the Fund  will  either  enter  into a
closing purchase  transaction or replace the GNMA certificate with a certificate
which represents  cover.  When the Fund closes its position or replaces the GNMA
certificate, it may realize an unanticipated loss and incur transaction costs.

    RISKS PERTAINING TO THE SECONDARY  MARKET.  An option position may be closed
out only in a secondary  market for an option of the same  series.  Although the
Fund will generally purchase or write only those options for which there appears
to be an active secondary market,  there is no assurance that a liquid secondary
market will exist for any particular option at any particular time, and for some
options no secondary  market may exist.  In such event, it might not be possible
to effect closing  transactions in particular options,  with the result that the
Fund would have to exercise its options in order to realize any profit and might
incur transaction costs in connection  therewith.  If the Fund as a covered call
option writer is unable to effect a closing purchase  transaction in a secondary
market,  it will not be able to sell the  underlying  security  until the option
expires or it delivers the underlying security upon exercise.

    Reasons for the absence of a liquid  secondary  market include the following
(i) insufficient trading interest in certain options;  (ii) restrictions imposed
on transactions;  (iii) trading halts, suspensions or other restrictions imposed
with  respect  to  particular   classes  or  series  of  options  or  underlying
securities;(iv)  interruption  of the normal  operations  on an Exchange or by a
broker; (v) inadequacy of the facilities of an Exchange,  the OCC or a broker to
handle current trading volume;  or (vi) a decision by one or more Exchanges or a
broker to discontinue the trading of options (or a particular class or series of
options), in which event the secondary market in that class or series of options
would cease to exist,  although  outstanding  options  that had been issued as a
result of trades would  generally  continue to be exercisable in accordance with
their terms.

    The hours of trading  for  options  on U.S.  government  securities  may not
conform to the hours during which the underlying  securities are traded.  To the
extent that the option  markets  close  before the  markets  for the  underlying
securities,  significant  price  and  rate  movements  can  take  place  in  the
underlying markets that cannot be reflected in the option markets.

               FUTURES CONTRACTS AND RELATED OPTIONS TRANSACTIONS
    The  Fund  intends  to enter  into  currency  and  other  financial  futures
contracts  as a hedge  against  changes  in  prevailing  levels of  interest  or
currency exchange rates to seek relative stability of principal and to establish
more  definitely  the  effective  return on  securities  held or  intended to be
acquired by the Fund or as a hedge  against  changes in the prices of securities
or currencies held by the Fund or to be acquired by the Fund. The Fund's hedging
may  include  sales of  futures  as an offset  against  the  effect of  expected
increases  in interest  or  currency  exchange  rates or  securities  prices and
purchases  of futures as an offset  against the effect of  expected  declines in
interest or currency exchange rates.

    For example, when the Fund anticipates a significant market or market sector
advance,  it will purchase a stock index futures contract as a hedge against not
participating in such advance at a time when the Fund is not fully invested. The
purchase of a futures contract serves as a temporary substitute for the purchase
of individual  securities which may then be purchased in an orderly fashion.  As
such purchases are made, an equivalent  amount of index based futures  contracts
would be terminated by offsetting sales. In contrast,  the Fund would sell stock
index  futures  contracts in  anticipation  of or in a general  market or market
sector  decline  that may  adversely  affect  the  market  value  of the  Fund's
portfolio.  To the  extent  that  the  Fund's  portfolio  changes  in  value  in
correlation  with a given  index,  the sale of futures  contracts  on that index
would  substantially  reduce the risk to the  portfolio  of a market  decline or
change in  interest  rates,  and,  by so doing,  provide an  alternative  to the
liquidation  of the Fund's  securities  positions and the resulting  transaction
costs.

    The Fund  intends to engage in  options  transactions  which are  related to
commodity  futures  contracts for hedging  purposes and in  connection  with the
hedging strategies described above.

    Although  techniques other than sales and purchases of futures contracts and
related  options  transactions  could be used to reduce the Fund's  exposure  to
interest  rate  and/or  market  fluctuations,  the Fund may be able to hedge its
exposure  more  effectively  and perhaps at a lower cost through  using  futures
contracts and related  options  transactions.  While the Fund does not intend to
take delivery of the instruments underlying futures contracts it holds, the Fund
does not intend to engage in such futures contracts for speculation.

FUTURES CONTRACTS
    Futures contracts are transactions in the commodities markets rather than in
the securities  markets.  A futures contract creates an obligation by the seller
to deliver to the buyer the  commodity  specified in the contract at a specified
future time for a specified price. The futures contract creates an obligation by
the buyer to accept  delivery from the seller of the commodity  specified at the
specified future time for the specified  price. In contrast,  a spot transaction
creates an  immediate  obligation  for the  seller to  deliver  and the buyer to
accept  delivery of and pay for an  identified  commodity.  In general,  futures
contracts  involve  transactions  in  fungible  goods such as wheat,  coffee and
soybeans.  However, in the last decade an increasing number of futures contracts
have  been  developed  which  specify  currencies,   financial   instruments  or
financially based indexes as the underlying commodity.

    U.S. futures contracts are traded only on national futures exchanges and are
standardized  as to  maturity  date and  underlying  financial  instrument.  The
principal  financial  futures  exchanges  in the United  States are The Board of
Trade of the City of Chicago, the Chicago Mercantile Exchange, the International
Monetary Market (a division of the Chicago  Mercantile  Exchange),  the New York
Futures  Exchange and the Kansas City Board of Trade.  Each exchange  guarantees
performance  under  contract  provisions  through  a  clearing  corporation,   a
nonprofit  organization  managed  by the  exchange  membership,  which  is  also
responsible for handling daily  accounting of deposits or withdrawals of margin.
A futures  commission  merchant  (Broker) effects each transaction in connection
with futures  contracts  for a  commission.  Futures  exchanges  and trading are
regulated  under the  Commodity  Exchange Act by the Commodity  Futures  Trading
Commission (CFTC) and National Futures Association (NFA).

INTEREST RATE FUTURES CONTRACTS
    The sale of an interest rate futures  contract  creates an obligation by the
Fund, as seller,  to deliver the type of financial  instrument  specified in the
contract at a specified  future time for a specified  price.  The purchase of an
interest rate futures  contract creates an obligation by the Fund, as purchaser,
to accept delivery of the type of financial  instrument specified at a specified
future  time  for a  specified  price.  The  specific  securities  delivered  or
accepted,  respectively, at settlement date, are not determined until at or near
that date. The  determination is in accordance with the rules of the exchange on
which the futures contract sale or purchase was made.

    Currently interest rate futures contracts can be purchased or sold on 90-day
U.S.  Treasury bills,  U.S.  Treasury bonds, U.S. Treasury notes with maturities
between 6 1/2 and 10 years,  Government  National  Mortgage  Association  (GNMA)
certificates,  90-day domestic bank  certificates of deposit,  90-day commercial
paper,  and 90-day  Eurodollar  certificates  of deposit.  It is  expected  that
futures   contracts  trading  in  additional   financial   instruments  will  be
authorized. The standard contract size is $100,000 for futures contracts in U.S.
Treasury bonds,  U.S. Treasury notes and GNMA  certificates,  and $1,000,000 for
the other designated  contracts.  While U.S. Treasury bonds, U.S. Treasury bills
and U.S.  Treasury  notes are  backed by the full  faith and  credit of the U.S.
government and GNMA certificates are guaranteed by a U.S. government agency, the
futures contracts in U.S. government  securities are not obligations of the U.S.
Treasury.

INDEX BASED FUTURES CONTRACTS
    It is expected  that bond index and other  financially  based index  futures
contracts  will be developed in the future.  It is  anticipated  that such index
based  futures  contracts  will be  structured  in the same  way as stock  index
futures  contracts  but will be measured by changes in interest  rates,  related
indexes or other  measures,  such as the consumer price index. In the event that
such futures  contracts are developed the Fund will sell interest rate index and
other index based futures  contracts to hedge against changes which are expected
to affect the Fund's portfolio.

    The purchase or sale of a futures contract differs from the purchase or sale
of a  security,  in that no price or premium is paid or  received.  Instead,  to
initiate trading an amount of cash, cash equivalents,  money market instruments,
or U.S.  Treasury bills equal to approximately 1 1/2% (up to 5%) of the contract
amount must be  deposited  by the Fund with the Broker.  This amount is known as
initial  margin.  The  nature of  initial  margin  in  futures  transactions  is
different from that of margin in security transactions.  Futures contract margin
does not  involve  the  borrowing  of  funds  by the  customer  to  finance  the
transactions.  Rather, the initial margin is in the nature of a performance bond
or good  faith  deposit  on the  contract  which is  returned  to the Fund  upon
termination of the futures  contract  assuming all contractual  obligations have
been satisfied.  The margin required for a particular futures contract is set by
the exchange on which the contract is traded, and may be significantly  modified
from time to time by the exchange during the term of the contract.

    Subsequent  payments,  called variation  margin,  to the Broker and from the
Broker,  are made on a daily basis as the value of the underlying  instrument or
index  fluctuates  making the long and short  positions in the futures  contract
more or less valuable, a process known as mark-to-market.  For example, when the
Fund has purchased a futures contract and the price of the underlying  financial
instrument or index has risen,  that  position will have  increased in value and
the Fund will receive from the Broker a variation  margin  payment equal to that
increase in value.  Conversely,  where the Fund has purchased a futures contract
and the price of the underlying financial instrument or index has declined,  the
position  would be less  valuable  and the  Fund  would  be  required  to make a
variation  margin payment to the Broker.  At any time prior to expiration of the
futures  contract,   the  Fund  may  elect  to  close  the  position.   A  final
determination of variation  margin is then made,  additional cash is required to
be paid to or released by the Broker, and the Fund realizes a loss or gain.

    The Fund  intends to enter into  arrangements  with its  custodian  and with
Brokers to enable its initial  margin and any  variation  margin to be held in a
segregated account by its custodian on behalf of the Broker.

    Although  interest  rate  futures  contracts  by their terms call for actual
delivery  or  acceptance  of  financial  instruments,  and index  based  futures
contracts  call for the  delivery  of cash equal to the  difference  between the
closing value of the index on the expiration  date of the contract and the price
at which the futures  contract is  originally  made,  in most cases such futures
contracts are closed out before the settlement date without the making or taking
of delivery.  Closing out a futures  contract  sale is effected by an offsetting
transaction  in which the Fund enters into a futures  contract  purchase for the
same aggregate amount of the specific type of financial  instrument or index and
same delivery date. If the price in the sale exceeds the price in the offsetting
purchase,  the Fund is paid the  difference  and thus  realizes  a gain.  If the
offsetting  purchase price exceeds the sale price,  the Fund pays the difference
and realizes a loss.  Similarly,  the closing out of a futures contract purchase
is ef-  fected by an  offsetting  transaction  in which the Fund  enters  into a
futures  contract sale. If the offsetting sale price exceeds the purchase price,
the Fund realizes a gain.  If the purchase  price  exceeds the  offsetting  sale
price the Fund  realizes a loss.  The  amount of the Fund's  gain or loss on any
transaction  is  reduced  or  increased,  respectively,  by  the  amount  of any
transaction costs incurred by the Fund.

    As an example of an  offsetting  transaction,  the  contractual  obligations
arising  from the sale of one contract of September  U.S.  Treasury  bills on an
exchange  may be  fulfilled  at any time  before  delivery  of the  contract  is
required (i.e., on a specified date in September,  the "delivery  month") by the
purchase of one contract of September U.S.  Treasury bills on the same exchange.
In such instance the difference  between the price at which the futures contract
was sold and the price paid for the  offsetting  purchase  after  allowance  for
transaction costs represents the profit or loss to the Fund.

    There can be no assurance, however, that the Fund will be able to enter into
an offsetting  transaction with respect to a particular contract at a particular
time. If the Fund is not able to enter into an offsetting transaction,  the Fund
will continue to be required to maintain the margin deposits on the contract and
to complete the contract according to its terms.

OPTIONS ON CURRENCY AND OTHER FINANCIAL FUTURES
    The Fund  intends to purchase  call and put  options on  currency  and other
financial  futures  contracts  and sell such  options to  terminate  an existing
position.  Options on currency and other financial futures contracts are similar
to options on stocks  except  that an option on a  currency  or other  financial
futures  contract gives the purchaser the right, in return for the premium paid,
to assume a position in a futures  contract (a long  position if the option is a
call and a short  position  if the option is a put)  rather  than to purchase or
sell stock,  currency or other  financial  instruments  at a specified  exercise
price at any time during the period of the option.  Upon exercise of the option,
the  delivery of the futures  position by the writer of the option to the holder
of the option will be accompanied by delivery of the accumulated  balance in the
writer's futures margin account.  This amount represents the amount by which the
market price of the futures contract at exercise exceeds, in the case of a call,
or is less than,  in the case of a put, the exercise  price of the option on the
futures  contract.  If an option is exercised  the last trading day prior to the
expiration  date of the option,  the  settlement  will be made  entirely in cash
equal to the  difference  between the exercise  price of the option and value of
the futures contract.

    The Fund  intends to use options on  currency  and other  financial  futures
contracts in connection with hedging strategies.  In the future the Fund may use
such options for other purposes.

PURCHASE OF PUT OPTIONS ON FUTURES CONTRACTS
    The  purchase of  protective  put  options on a currency or other  financial
futures  contract is analagous to the purchase of protective  puts on individual
stocks,  where  an  absolute  level  of  protection  is  sought  below  which no
additional  economic  loss would be  incurred  by the Fund.  Put  options may be
purchased  to hedge a portfolio of stocks or debt  instruments  or a position in
the futures contract upon which the put option is based.

PURCHASE OF CALL OPTIONS ON FUTURES CONTRACTS
    The  purchase  of a call  option on a currency  or other  financial  futures
contract   represents  a  means  of  obtaining   temporary  exposure  to  market
appreciation  at limited  risk. It is analogous to the purchase of a call option
on an individual  stock which can be used as a substitute  for a position in the
stock  itself.  Depending  on the  pricing of the option  compared to either the
futures  contract  upon which it is based,  or upon the price of the  underlying
financial  instrument or index itself, the purchase of a call option may be less
risky than the ownership of the interest rate or index based futures contract or
the underlying securities.  Call options on currency and other financial futures
contracts  may be  purchased  to hedge  against an interest  rate  increase or a
market advance when the Fund is not fully invested.

USE OF NEW INVESTMENT TECHNIQUES INVOLVING COMMODITY FUTURES CONTRACTS
OR RELATED OPTIONS
    The Fund may employ new investment  techniques  involving currency and other
financial  futures  contracts  and  related  options.  The Fund  intends to take
advantage of new  techniques in these areas which may be developed  from time to
time and which are consistent  with the Fund's  investment  objective.  The Fund
believes that no additional  techniques  have been  identified for employment by
the Fund in the foreseeable future other than those described above.

LIMITATIONS ON PURCHASE AND SALE OF FUTURES CONTRACTS AND RELATED
OPTIONS ON SUCH FUTURES CONTRACTS
    The Fund will not enter  into a futures  contract  if, as a result  thereof,
more than 5% of the Fund's  total  assets  (taken at market value at the time of
entering  into the  contract)  would be  committed  to margin  deposits  on such
futures contracts.

    The Fund intends that its futures contracts and related options transactions
will be  entered  into  for  traditional  hedging  purposes.  That  is,  futures
contracts  will be sold to protect  against a decline in the price of securities
that the Fund owns or futures  contracts  will be  purchased to protect the Fund
against an increase in the price of securities it intends to purchase.  The Fund
does not intend to enter into futures contracts for speculation.

    In instances  involving  the purchase of futures  contracts by the Fund,  an
amount of cash and cash  equivalents  equal to the market  value of the  futures
contracts  will be deposited in a segregated  account with the Fund's  Custodian
and/or in a margin  account  with a Broker to  collateralize  the  position  and
thereby insure that the use of such futures is unleveraged.

FEDERAL INCOME TAX TREATMENT
    For federal income tax purposes, the Fund is required to recognize as income
for each taxable year its net unrealized  gains and losses on futures  contracts
as of the end of the year as well as those  actually  realized  during the year.
Any gain or loss recognized with respect to a futures  contract is considered to
be 60% long term and 40% short term, without regard to the holding period of the
contract. In the case of a futures transaction classified as a "mixed straddle,"
the  recognition  of losses may be deferred to a later taxable year. The federal
income tax treatment of gains or losses from  transactions in options on futures
is unclear.

    In order  for the  Fund to  continue  to  qualify  for  federal  income  tax
treatment as a regulated  investment  company,  at least 90% of its gross income
for a taxable year must be derived from qualifying income. Any net gain realized
from the closing out of futures contracts,  for purposes of the 90% requirement,
will be  qualifying  income.  In addition,  gains  realized on the sale or other
disposition  of  securities  held for less than three  months must be limited to
less  than 30% of the  Fund's  annual  gross  income.  The 1986 Tax Act  added a
provision   which   effectively   treats  both  positions  in  certain   hedging
transactions as a single transaction for the purpose of the 30% requirement. The
provision  provides that, in the case of any "designated  hedge,"  increases and
decreases  in the value of  positions  of the  hedge  are to be  netted  for the
purposes of the 30% requirement.  However,  in certain  situations,  in order to
avoid realizing a gain within a three month period,  the Fund may be required to
defer the closing out of a contract  beyond the time when it would  otherwise be
advantageous to do so.

RISKS OF FUTURES CONTRACTS
    Currency and other financial  futures  contracts prices are volatile and are
influenced,  among other things, by changes in stock prices,  market conditions,
prevailing  interest  rates and  anticipation  of future  stock  prices,  market
movements  or  interest  rate  changes,  all of which in turn  are  affected  by
economic  conditions,  such as  government  fiscal  and  monetary  policies  and
actions, and national and international political and economic events.

    At best, the correlation  between changes in prices of futures contracts and
of  the  securities  being  hedged  can  be  only  approximate.  The  degree  of
imperfection of correlation  depends upon  circumstances,  such as variations in
speculative  market demand for futures  contracts and for securities,  including
technical  influences  in futures  contracts  trading;  differences  between the
securities being hedged and the financial instruments and indexes underlying the
standard futures contracts  available for trading,  in such respects as interest
rate levels,  maturities  and  creditworthiness  of issuers,  or  identities  of
securities comprising the index and those in the Fund's portfolio. A decision of
whether, when and how to hedge involves the exercise of skill and judgment,  and
even a well-conceived hedge may be unsuccessful to some degree because of market
behavior or unexpected interest rate trends.

    Because of the low margin deposits  required,  futures  trading  involves an
extremely  high  degree of  leverage.  As a result,  a  relatively  small  price
movement in a futures contract may result in immediate and substantial  loss, as
well as gain, to the investor.  For example, if at the time of purchase,  10% of
the value of the futures  contract is deposited as margin, a 10% decrease in the
value  of the  futures  contract  would  result  in a total  loss of the  margin
deposit,  before any deduction for the  transaction  costs,  if the account were
then closed out, and a 15% decrease  would result in a loss equal to 150% of the
original  margin  deposit.  Thus,  a purchase or sale of a futures  contract may
result  in losses in excess of the  amount  invested  in the  futures  contract.
However,  the Fund would presumably have sustained comparable losses if, instead
of  entering  into the  futures  contract,  it had  invested  in the  underlying
financial  instrument.  Furthermore,  in order to be  certain  that the Fund has
sufficient assets to satisfy its obligations under a futures contract,  the Fund
will  establish a segregated  account in connection  with its futures  contracts
which will hold cash or cash equivalents  equal in value to the current value of
the underlying instruments or indices less the margins on deposit.

    Most U.S.  futures  exchanges  limit the amount of fluctuation  permitted in
futures contract prices during a single trading day. The daily limit establishes
the maximum  amount that the price of a futures  contract  may vary either up or
down from the previous day's  settlement  price at the end of a trading session.
Once the daily  limit has been  reached in a  particular  type of  contract,  no
trades may be made on that day at a price  beyond  that  limit.  The daily limit
governs only price movement  during a particular  trading day and therefore does
not limit  potential  losses  because the limit may prevent the  liquidation  of
unfavorable  positions.  Futures contract prices have occasionally  moved to the
daily  limit for  several  consecutive  trading  days with little or no trading,
thereby  preventing prompt  liquidation of futures positions and subjecting some
futures traders to substantial losses.

RISKS OF OPTIONS ON FUTURES CONTRACTS
    In addition to the risks  described  above for currency and other  financial
futures  contracts,  there are  several  special  risks  relating  to options on
futures  contracts.  The ability to  establish  and close out  positions on such
options will be subject to the development and maintenance of a liquid secondary
market.  There is no assurance that a liquid secondary market will exist for any
particular  contract  or at any  particular  time.  The Fund  will not  purchase
options on any futures contract unless and until it believes that the market for
such options has developed  sufficiently  that the risks in connection with such
options are not greater than the risks in connection with the futures contracts.
Compared  to the use of  futures  contracts,  the  purchase  of  options on such
futures  involves less  potential risk to the Fund because the maximum amount at
risk is the premium  paid for the options  (plus  transaction  costs).  However,
there may be circumstances when the use of an option on a futures contract would
result in a loss to the Fund,  even though the use of a futures  contract  would
not, such as when there is no movement in the level of the futures contract.

                         FOREIGN CURRENCY TRANSACTIONS
    The Fund may invest in securities denominated in foreign currencies, and the
Fund  temporarily may hold funds in foreign  currencies.  Thus, the Fund's share
value will be affected by changes in exchange rates.

FORWARD CURRENCY CONTRACTS
    As one way of managing  exchange  rate risk,  the Fund may engage in forward
currency  exchange  contracts  (agreements  to purchase or sell  currencies at a
specified  price  and  date).  Under the  contract,  the  exchange  rate for the
transaction  (the amount of currency  the Fund will  deliver or receive when the
contract is completed) is fixed when the Fund enters into the contract. The Fund
usually will enter into these  contracts to stabilize the U.S. dollar value of a
security it has agreed to buy or sell. The Fund also may use these  contracts to
hedge the U.S.  dollar value of a security it already owns,  particularly if the
Fund  expects a  decrease  in the  value of the  currency  in which the  foreign
security is  denominated.  Although  the Fund will attempt to benefit from using
forward contracts, the success of its hedging strategy will depend on Keystone's
ability  to  predict  accurately  the  future  exchange  rates  between  foreign
currencies and the U.S. dollar. The value of the Fund's investments  denominated
in foreign  currencies will depend on the relative  strength of those currencies
and the U.S.  dollar,  and the Fund may be affected  favorably or unfavorably by
changes in the exchange rate or exchange  control  regulations  between  foreign
currencies and the dollar.  Changes in foreign currency  exchange rates also may
affect the value of dividends and interest earned,  gains and losses realized on
the sale of  securities  and net  investment  income  and gains,  if any,  to be
distributed to shareholders by the Fund.

CURRENCY FUTURES CONTRACTS
    Currency futures contracts are bilateral  agreements under which two parties
agree  to take  or make  delivery  of a  specified  amount  of a  currency  at a
specified  future  time for a  specified  price.  Trading  of  currency  futures
contracts in the United States is regulated under the Commodity  Exchange Act by
the Commodity Futures Trading Commission (CFTC) and National Futures Association
(NFA).  Currently the only national  futures  exchange on which currency futures
are  traded  is the  International  Monetary  Market of the  Chicago  Mercantile
Exchange.  Foreign  currency futures trading is conducted in the same manner and
subject to the same  regulations  as trading in  interest  rate and index  based
futures.  The Fund  intends to only engage in  currency  futures  contracts  for
hedging  purposes,  and not for  speculation.  The Fund may  engage in  currency
futures  contracts for other  purposes if authorized to do so by the Board.  The
hedging  strategies  which will be used by the Fund in  connection  with foreign
currency  futures  contracts  are similar to those  described  above for forward
foreign currency exchange contracts.

    Currently  currency  futures  contracts  for  the  British  Pound  Sterling,
Canadian Dollar, Dutch Guilder, Deutsche Mark, Japanese Yen, Mexican Peso, Swiss
Franc and French  Franc can be purchased  or sold for U.S.  dollars  through the
International  Monetary Market. It is expected that futures contracts trading in
additional  currencies  will be  authorized.  The  standard  contract  sizes are
L125,000  for the  Pound,  125,000  for the  Guilder,  Mark  and  Swiss  Francs,
C$100,000 for the Canadian  Dollar,  Y12,500,000  for the Yen, and 1,000,000 for
the Peso. In contrast to Forward Currency Exchange Contracts which can be traded
at any time,  only four value dates per year are available,  the third Wednesday
of March, June, September and December.

FOREIGN CURRENCY OPTIONS TRANSACTIONS
    Foreign  currency options (as opposed to futures) are traded in a variety of
currencies  in both the United  States and  Europe.  On the  Philadelphia  Stock
Exchange, for example,  contracts for half the size of the corresponding futures
contracts  on the  Chicago  Board  Options  Exchange  are traded with up to nine
months  maturity in marks,  sterling,  yen,  Swiss francs and Canadian  dollars.
Options  can be  exercised  at any time during the  contract  life and require a
deposit subject to normal margin requirements.  Since a futures contract must be
exercised,  the Fund must continually make up the margin balance. As a result, a
wrong  price  move  could  result  in the Fund  losing  more  than the  original
investment as it cannot walk away from the futures  contract as it can an option
contract.

    The Fund  will  purchase  call and put  options  and sell  such  options  to
terminate  an  existing  position.  Options on foreign  currency  are similar to
options on stocks  except that an option on an interest  rate and/or index based
futures  contract gives the purchaser the right, in return for the premium paid,
to purchase or sell foreign currency,  rather than to purchase or sell stock, at
a specified exercise price at any time during the period of the option.

    The Fund intends to use foreign  currency option  transactions in connection
with hedging strategies.

PURCHASE OF PUT OPTIONS ON FOREIGN CURRENCIES
    The purchase of protective put options on a foreign currency is analagous to
the purchase of protective puts on individual stocks, where an absolute level of
protection is sought below which no  additional  economic loss would be incurred
by the Fund. Put options may be purchased to hedge a portfolio of foreign stocks
or foreign debt instruments or a position in the foreign currency upon which the
put option is based.

PURCHASE OF CALL OPTIONS ON FOREIGN CURRENCIES
    The  purchase of a call  option on foreign  currency  represents  a means of
obtaining  temporary  exposure to market  appreciation  at limited  risk.  It is
analogous to the purchase of a call option on an  individual  stock which can be
used as a  substitute  for a  position  in the stock  itself.  Depending  on the
pricing of the option  compared to either the foreign  currency upon which it is
based, or upon the price of the foreign stock or foreign debt  instruments,  the
purchase  of a call option may be less risky than the  ownership  of the foreign
currency or the foreign  securities.  The Fund would purchase a call option on a
foreign  currency to hedge  against an  increase  in the  foreign  currency or a
foreign market advance when the Fund is not fully invested.

    The Fund may employ new  investment  techniques  involving  forward  foreign
currency exchange  contracts,  foreign currency futures contracts and options on
foreign  currencies in order to take  advantage of new techniques in these areas
which may be  developed  from time to time and  which  are  consistent  with the
Fund's  investment  objective.  The Fund believes that no additional  techniques
have been identified for employment by the Fund in the foreseeable  future other
than those described above.

CURRENCY TRADING RISKS
    Currency  exchange  trading may involve  significant  risks.  The four major
types of risk the Fund faces are exchange rate risk,  interest rate risk, credit
risk and country risk.

EXCHANGE RATE RISK
    Exchange rate risk results from the movement up and down of foreign currency
values in response to shifting  market supply and demand.  When the Fund buys or
sells a foreign currency, an exposure called an open position is created.  Until
the time that  position  can be  "covered"  by selling  or buying an  equivalent
amount of the same  currency,  the Fund is exposed to the risk that the exchange
rate might move against it. Since  exchange rate changes can readily move in one
direction,  a  position  carried  overnight  or over a number  of days  involves
greater risk than one carried a few minutes or hours. Techniques such as foreign
currency  forward and futures  contracts  and  options on foreign  currency  are
intended to be used by the Fund to reduce exchange rate risk.


MATURITY GAPS AND INTEREST RATE RISK
    Interest  rate risk  arises  whenever  there are  mismatches  or gaps in the
maturity  structure of the Fund's foreign exchange currency  holdings,  which is
the total of its outstanding spot and forward or futures contracts.

    Foreign currency transactions often involve borrowing short term and lending
longer term to benefit from the normal  tendency of interest  rates to be higher
for longer maturities.  However in foreign exchange trading,  while the maturity
pattern of interest rates for one currency is important,  it is the differential
between interest rates for two currencies that is decisive.

CREDIT RISK
    Whenever the Fund enters into a foreign exchange contract,  it faces a risk,
however small, that the counterparty  will not perform under the contract.  As a
result there is a credit risk, although no extension of "credit" is intended. To
limit credit risk,  the Fund  intends to evaluate the  creditworthiness  of each
other  party.  The Fund does not  intend to trade more than 5% of its net assets
under foreign exchange contracts with one party.

    Credit  risk  exists  because  the  Fund's  counterparty  may be  unable  or
unwilling to fulfill its  contractual  obligations  as a result of bankruptcy or
insolvency or when foreign exchange  controls prohibit  payment.  In any foreign
exchange transaction,  each party agrees to deliver a certain amount of currency
to the other on a particular date. In establishing its hedges the Fund relies on
each contract being completed. If the contract is not performed, then the Fund's
hedge is  eliminated,  and the Fund is exposed to any changes in exchange  rates
since the contract was  originated.  To put itself in the same position it would
have  been in had the  contract  been  performed,  the Fund  must  arrange a new
transaction.  However, the new transaction may have to be arranged at an adverse
exchange  rate.  The trustee for a bankrupt  company may elect to perform  those
contracts  which are  advantageous  to the company but disclaim those  contracts
which are disadvantageous, resulting in losses to the Fund.

    Another form of credit risk stems from the time zone differences between the
U.S.  and foreign  nations.  If the Fund sells  sterling it  generally  must pay
pounds  to a  counterparty  earlier  in the day  than it will be  credited  with
dollars in New York. In the intervening  hours, the buyer can go into bankruptcy
or can be  declared  insolvent.  Thus,  the dollars may never be credited to the
Fund.

COUNTRY RISK
    At one  time  or  another,  virtually  every  country  has  interfered  with
international  transactions in its currency.  Interference has taken the form of
regulation of the local exchange market,  restrictions on foreign  investment by
residents or limits on inflows of investment funds from abroad. Governments take
such measures for example to improve control over the domestic banking system or
to  influence  the  pattern of  receipts  and  payments  between  residents  and
foreigners.   In  those  cases,  restrictions  on  the  exchange  market  or  on
international  transactions  are intended to affect the level or movement of the
exchange rate.  Occasionally  a serious  foreign  exchange  shortage may lead to
payment  interruptions or debt servicing  delays, as well as interference in the
exchange market.  It has become  increasingly  difficult to distinguish  foreign
exchange or credit risk from country risk.

    Changes in regulations or restrictions usually do have an important exchange
market impact.  Most  disruptive  are changes in rules which  interfere with the
normal payments mechanism.  If government  regulations change and a counterparty
is either  forbidden to perform or is required to do something  extra,  then the
Fund might be left with an unintended  open  position or an unintended  maturity
mismatch.  Dealing with such  unintended long or short positions could result in
unanticipated costs to the Fund.

    Other changes in official  regulations  influence  international  investment
transactions.  If one of the  factors  affecting  the  buying  or  selling  of a
currency  changes,  the  exchange  rate is likely to  respond.  Changes  in such
controls  often are  unpredictable  and can create a  significant  exchange rate
response.

    Many major  countries  have moved  toward  liberalization  of  exchange  and
payments   restrictions   in  recent  years  or  accepted  the  principle   that
restrictions  should be relaxed.  A few  industrial  countries have moved in the
other direction.  Important liberalizations were carried out by Switzerland, the
United Kingdom and Japan.  They  dismantled  mechanisms for  restricting  either
foreign exchange inflows  (Switzerland),  outflows (Britain) or elements of both
(Japan). By contrast, France and Mexico have recently tightened foreign exchange
controls.

     Overall,  many  exchange  markets  are still  heavily  restricted.  Several
countries limit access to the forward market to companies  financing  documented
export or import  transactions  in an effort to insulate  the market from purely
speculative  activities.  Some of these countries  permit local traders to enter
into forward contracts with residents but prohibit certain forward  transactions
with  nonresidents.  By  comparison,  other  countries  have strict  controls on
exchange  transactions  by  residents,  but permit  free  exchange  transactions
between local traders and non-residents. A few countries have established tiered
markets,  funneling  commercial  transactions  through one market and  financial
transactions through another. Outside the major industrial countries, relatively
free  foreign  exchange  markets  are  rare and  controls  on  foreign  currency
transactions are extensive.

    Another aspect of country risk has to do with the possibility  that the Fund
may be dealing  with a foreign  trader  whose home  country is facing a payments
problem.  Even  though the  foreign  trader  intends  to perform on its  foreign
exchange  contracts,  the contracts are tied to other external  liabilities  the
country has incurred.  As a result performance may be delayed, and can result in
unanticipated  cost to the Fund.  This aspect of country risk is a major element
in the Fund's credit judgment as to with whom it will deal and in what amounts.

   *Prior to June 30, 1987, net commissions paid on new sales of shares under the Fund's Rule 12b-1 Distribution Plan had 
    been treated for both financial statement and tax purposes as capital charges. On June 11, 1987, the Securities and 
    Exchange Commission adopted a rule which required for financial statements for the periods ended on or after June 30, 
    1987, that net commissions paid under Rule 12b-1 be treated as operating expenses rather than capital charges. 
    Accordingly, beginning with the year ended December 31, 1987, the Fund's financial statements reflect 12b-1 
    Distribution Plan expenses (i.e., shareholder service fees plus commissions paid net of deferred sales charges 
    received by the Fund) as a component of net investment income. 
  **Effective January 1, 1993 the Fund adopted Statement of Position 93-2: Determination, Disclosure, and Financial 
    Statement Presentation of Income, Capital Gain and Return of Capital Distributions by Investment Companies. As a 
    result, distribution amounts exceeding book basis net investment income (or tax basis net income on a temporary basis) 
    are presented as "Distributions in excess of net investment income." Similarly, capital gain distributions in excess 
    of book basis capital gains (or tax basis capital gains on a temporary basis) are presented as "Distributions in 
    excess of realized capital gains." For the fiscal years ended December 31, 1992, 1991 and 1990, distributions in 
    excess of book basis net income were charged to paid-in capital. 
 ***Calculation based on average shares outstanding. 
****Excluding applicable sales charges.

A. Tax-exempt bonds are stated on the basis of valuations provided by a 
pricing service, approved by the Board of Trustees, that uses information with 
respect to transactions in bonds, quotations from bond dealers, market 
transactions in comparable securities and various relationships between 
securities in determining value. Non-tax-exempt securities for which market 
quotations are readily available are valued at the price quoted which, in the 
opinion of the Board of Trustees or their representative, most nearly 
represents their market value. 

Short-term investments which are purchased with maturities of sixty days or 
less are valued at amortized cost (original purchase cost as adjusted for 
amortization of premium or accretion of discount) which when combined with 
accrued interest approximates market. Short-term investments maturing in more 
than sixty days for which market quotations are readily available are valued 
at current market value. Short-term investments maturing in more than sixty 
days when purchased which are held on the sixtieth day prior to maturity are 
valued at amortized cost (market value on the sixtieth day adjusted for 
amortization of premium or accretion of discount) which when combined with 
accrued interest approximates market. All other securities and other assets 
are valued at fair value as determined in good faith using methods prescribed 
by the Board of Trustees. 

B. A futures contract is an agreement between two parties to buy and sell a 
specific amount of a commodity, security, financial instrument, or, in the 
case of a stock index, cash at a set price on a future date. Upon entering 
into a futures contract, the Fund is required to deposit with a broker an 
amount ("initial margin") equal to a certain percentage of the purchase price 
indicated in the futures contract. Subsequent payments ("variation margin") 
are made or received by the Fund each day, as the value of the underlying 
instrument or index fluctuates, and are recorded for book purposes as 
unrealized gains or losses by the Fund. For federal tax purposes, any futures 
contracts which remain open at fiscal year-end are marked-to-market and the 
resultant net gain or loss is included in federal taxable income. 

C. Securities transactions are accounted for on the trade date. Realized gains 
and losses are recorded on the identified cost basis. Interest income is 
recorded on the accrual basis. All premiums and original issue discounts are 
amortized/accreted for both financial reporting and federal income tax 
purposes. 

D. The Fund has qualified, and intends to qualify in the future, as a 
regulated investment company under the Internal Revenue Code of 1986, as 
amended ("Internal Revenue Code"). Thus, the Fund is relieved of any federal 
income tax liability by distributing all 

<PAGE>
 
of its net investment income and net capital gains, if any, to its 
shareholders. The Fund intends to avoid excise tax liability by making the 
required distributions under the Internal Revenue Code. 

E. When the Fund enters into a repurchase agreement (a purchase of securities 
whereby the seller agrees to repurchase the securities at a mutually agreed 
upon date and price) the repurchase price of the securities will generally 
equal the amount paid by the Fund plus a negotiated interest amount. The 
seller under the repurchase agreement will be required to provide securities 
("collateral") to the Fund whose value will be maintained at an amount not 
less than the repurchase price, and which generally will be maintained at 101% 
of the repurchase price. The Fund monitors the value of collateral on a daily 
basis, and if the value of collateral falls below required levels, the Fund 
intends to seek additional collateral from the seller or terminate the 
repurchase agreement. If the seller defaults, the Fund would suffer a loss to 
the extent that the proceeds from the sale of the underlying securities were 
less than the repurchase price. Any such loss would be increased by any cost 
incurred on disposing of such securities. If bankruptcy proceedings are 
commenced against the seller under the repurchase agreement, the realization 
on the collateral may be delayed or limited. Repurchase agreements entered 
into by the Fund will be limited to transactions with dealers or domestic 
banks believed to present minimal credit risks, and the Fund will take 
constructive receipt of all securities underlying repurchase agreements until 
such agreements expire. 

F. The Fund distributes net investment income to shareholders monthly and net 
capital gains, if any, annually. Distributions from net investment income are 
determined in accordance with income tax regulations. Dividends from net 
investment income can exceed the Fund's book basis net investment income. 
Effective January 1, 1993, the Fund adopted Statement of Position 93-2: 
Determination, Disclosure, and Financial Statement Presentation of Income, 
Capital Gain and Return of Capital Distributions by Investment Companies. As a 
result, the Fund changed the financial statement classification of 
distributions to shareholders to more clearly reflect the differences between 
financial statement amounts available for distribution and amounts distributed 
to comply with income tax regulations. Accordingly, the following 
reclassifications have been made to the capital accounts in the year ended 
December 31, 1993; a decrease in paid-in capital of $22,347,918, an increase 
in undistributed net investment income of $12,495,901, and an increase in 
accumulated net realized gains (losses) on investment transactions of 
$9,852,017. The significant difference between financial statement amounts 
available for distribution and distributions made in accordance with income 
tax regulations is due to the difference in recognition of a deduction for 
12b-1 Distribution Plan charges. 

2. Capital Share Transactions 

The Declaration of Trust authorizes the issuance of an unlimited number of 
shares of beneficial interest with no par value. Transactions in shares of the 
Fund were as follows: 

<PAGE>
 

                                   Year Ended December 31, 
                                      1993         1992 
Shares sold                         20,470,708   46,460,519 
Shares redeemed                    (20,802,266) (13,808,422) 
Shares issued in reinvestment 
  of distributions from net 
  investment income and in 
  excess of net investment income    5,196,577    4,725,734 
Realized gain-net                    5,110,384    1,327,807 
Net increase                         9,975,403   38,705,638 

The Fund bears some of the costs of selling its shares under a Distribution 
Plan adopted pursuant to Rule 12b-1 under the Investment Company Act of 1940. 
The Distribution Plan provides that the Fund may incur certain expenses which 
may not exceed a maximum amount equal to 0.3125% of the Fund's average daily 
net assets for any quarter occurring after the inception of the Distribution 
Plan. Under the Distribution Plan, the Fund pays Keystone Distributors, Inc. 
("KDI"), the principal underwriter and a wholly-owned subsidiary of Keystone, 
amounts which in total may not exceed the Distribution Plan maximum. 

In connection with the Distribution Plan and subject to the limitations 
discussed below, Fund shares are offered for sale at net asset value without 
any initial sales charge. From the amounts received by KDI in connection with 
the Distribution Plan, and subject to the limitations discussed below, KDI 
generally pays brokers or others a commission equal to 3% of the price paid to 
the Funds for each sale of Fund shares as well as a shareholder service fee at 
a rate of 0.25% per annum of the net asset value of the shares sold by such 
brokers or others and remaining outstanding on the books of the Fund for 
specified periods. 

To the extent Fund shares are redeemed within four calendar years of original 
issuance, the Fund may be eligible to receive a deferred sales charge from the 
investor as partial reimbursement for sales commissions previously paid on 
those shares. This charge is based on declining rates, which begin at 4.0%, 
applied to the lesser of the net asset value of shares redeemed or the total 
cost of such shares. 

A new rule of the National Association of Securities Dealers, Inc. ("NASD 
Rule") limits the annual expenditures, which the Fund may incur under the 
Distribution Plan to 1%, of which 0.75% may be used to pay such distribution 
expenses and 0.25% may be used to pay shareholder service fees. The new NASD 
Rule also limits the aggregate amount which the Fund may pay for such 
distribution costs to 6.25% of gross share sales since the inception of the 
Fund's 12b-1 Distribution Plan, plus interest at the prime rate plus 1% on 
unpaid amounts thereof (less any contingent deferred sales charges paid by the 
shareholders to KDI). 

The Fund has operated its Distribution Plan in accordance with both the Plan 
and the NASD Rule since July 8, 1992, except that until July 7, 1993, maximum 
annual payments with respect to Net Asset Value as represented by shares sold 
prior to January 1, 1992 remained at the current rate of 0.3125% quarterly 
(approximately 1.25% annually). 

KDI intends, but is not obligated, to continue to pay or accrue distribution 
charges which exceed current annual payments permitted to be received by KDI 
from the Fund. KDI intends to seek full payment of such charges from the Fund 
(together with annual interest thereon at the prime rate plus one percent) at 
such time in the future as, and to the extent that, payment thereof by the 
Fund would be within permitted limits. KDI currently intends to seek payment 
of interest only on such charges paid or accrued by KDI subsequent to January 
1, 1992. 

<PAGE>
 
Commencing on July 8, 1992, contingent deferred sales charges applicable to 
shares of the Fund issued after January 1, 1992 have, to the extent permitted 
by the NASD Rule, been paid to KDI rather than to the Fund. 

During the year ended December 31, 1993, the Fund recovered $373,564 in 
deferred sales charges. During the year, the Fund paid KDI $16,608,165 under 
the Distribution Plan, of which $4,272,087 represented repayment of amounts 
("advances") paid by KDI during the year or in previous years in excess of 
amounts received by KDI under the Distribution Plan. The amount paid by the 
Fund under its Distribution Plan, net of deferred sales charges, was 
$16,234,601 (1.06% of the Fund's average daily net asset value during the 
year). During the year, KDI retained $9,241,496 and paid commissions on new 
sales and transfer agent fees to dealers and others of $7,366,669. During the 
year, KDI received $482,452 in deferred sales charges, reducing total advances 
outstanding to 8,498,955 (0.55% of the Fund's net asset value as of December 
31, 1993). 

3. Securities Transactions 

For the year ended December 31, 1993, purchases and sales of investment 
securities were as follows: 

                            Cost of        Proceeds 
                           Purchases      from Sales 
Tax-exempt investments  $1,124,995,844  $1,122,509,383 
Short-term commercial 
  and tax-exempt notes     697,351,597     712,860,332 
                        $1,822,347,441  $1,835,369,715 

4. Investment Management and Transactions with Affiliates 

Under the terms of the Investment Management Agreement between KMI and the 
Fund, dated December 29, 1989, KMI provides investment management and 
administrative services to the Fund, as well as certain additional operating 
services, facilities and supplies. In return, KMI is paid monthly, (i) a 
management fee calculated daily at a rate of 2.0% of the Fund's gross 
investment income plus an amount determined by applying percentage rates 
starting at 0.50% and declining as net assets increase, to 0.25% per annum, to 
the net asset value of the Fund, and (ii) an amount equal to KMI's 
reimbursable expenses accrued during the year in providing such additional 
services. KMI has entered into an Investment Advisory Agreement with Keystone, 
dated December 30, 1989, under which Keystone provides investment advisory and 
management services to the Fund and receives for its services an annual fee 
representing 85% of the management fee received by KMI. 

During the year ended December 31, 1993, the Fund paid or accrued to KMI 
investment management and administrative services fees of $8,995,945. Included 
in this amount is the management fee of $6,507,055, which represented 0.43% of 
the Fund's average net assets on an annualized basis. Of such management fee 
paid to KMI, $5,530,997 was paid to Keystone for its services to the Fund. 

Also included in the total investment management and administrative services 
fee paid by the Fund were the following approximate amounts incurred by KMI 
(and reimbursed by the Fund) in providing or obtaining for the Fund the 
additional operating services, facilities and supplies required by the 
Agreement: transfer agent fees, $1,657,577, audit and legal fees, $95,049, 
custodian fees, $422,122, printing and supplies, $93,508, and registration 
fees, $141,869, and other, $78,765. 

During the year ended December 31, 1993, the Fund paid or accrued to KIRC 
$29,735 for certain 

<PAGE>
 
accounting services and $1,657,577 for transfer agent fees. This amount for 
transfer agent fees services is included in the payments made by KMI described 
in the preceding paragraph. 

5. Distributions to Shareholders 

The net investment income of the Fund (interest income accrued as earned, less 
expenses of the Fund) is determined as of the normal close of trading on the 
New York Stock Exchange each business day on which the exchange is open. The 
net investment income so determined each day is declared as a dividend to 
shareholders of record at the time of such determination and is distributed 
promptly after the end of each calendar month. Any net realized short-term and 
long-term capital gains in excess of carried-over losses, will be distributed 
annually. All distributions of net investment income will be paid in cash 
unless the shareholder has directed that they be reinvested, in which case 
such reinvestment will be at the net asset value on the last business day of 
the month in which declared. Any distributions of capital gains will be 
reinvested in additional shares of the Fund at net asset value on the record 
date of the month in which declared unless the shareholder has specified that 
they wish to receive cash. Shares acquired through reinvestment of net 
investment income or capital gains are not subject to contingent deferred 
sales charges.

highlights are the responsibility of the Fund's management. Our responsibility 
is to express an opinion on these financial statements and financial 
highlights based on our audits. 

We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements and 
financial highlights are free of material misstatement. An audit includes 
examining, on a test basis, evidence supporting the amounts and disclosures in 
the financial statements. Our procedures included confirmation of securities 
owned as of December 31, 1993 by correspondence with the custodian and 
brokers. An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audits provide a 
reasonable basis for our opinion. 

In our opinion, the financial statements and financial highlights referred to 
above present fairly, in all material respects, the financial position of 
Keystone Tax Free Fund, as of December 31, 1993, the results of its operations 
for the year then ended, the changes in its net assets for each of the years
